Building a product without validating the market is gambling. And unlike a casino, the odds are not printed on the table. You can spend months building something brilliant that nobody wants, and you will not know until after the launch.

This checklist exists to prevent that. It is a 15-step process for validating whether a niche market can support your product idea before you invest serious time and money building it. Each step includes what to do, how to do it, what tools to use, what good results look like, and the most common mistake people make at that stage.

The checklist is sequential. Each step builds on the previous one. If a step fails, you either pivot the idea or stop entirely. Reaching the end of the checklist with passing results at every step means you have strong evidence that your idea is worth building.

Step 1: Define the Niche in One Sentence

What to do: Write a single sentence that describes your niche, your target customer, and the problem you solve.

Format: "[Product type] that helps [specific audience] [solve specific problem]."

Examples:

  • "A Chrome extension that helps recruiters extract candidate data from LinkedIn profiles automatically."
  • "A SaaS dashboard that helps Etsy sellers track which listings are underperforming and why."
  • "A scheduling tool that helps pet groomers manage appointments and track pet-specific notes."

Why this matters: Vague ideas produce vague results. If you cannot describe your niche in one sentence, you do not understand it well enough to validate it. The sentence forces clarity on who you are serving and what problem you are solving.

Tools: None needed. Just a text editor and honest thinking.

What good looks like: Your sentence names a specific audience (not "businesses" or "people"), a specific problem (not "improve their workflow"), and implies a specific solution type.

Common mistake: Being too broad. "A productivity tool for professionals" is not a niche. "A time-tracking extension for freelance designers who bill hourly" is a niche. Narrow beats broad at this stage. You can always expand later.

Step 2: Prove the Problem Exists

What to do: Find at least 10 independent pieces of evidence that real people experience the problem you described in Step 1.

Evidence sources:

Source What to Search For Strong Signal
Reddit "I wish there was...", "does anyone know a tool for...", complaints about existing solutions Multiple posts with significant upvotes and comments
Hacker News Problem descriptions in comment threads, "Ask HN" posts about the topic Engagement from multiple users, not just one person's blog post
X (Twitter) Frustration tweets, tool requests, workflow complaints Recurring theme from different users over time
Industry forums Domain-specific discussions about the problem Professionals describing the problem in work context
G2/Capterra reviews Negative reviews of existing tools mentioning missing features Consistent complaints across multiple competing products
Quora Questions about how to solve the specific problem Questions with many views and answers

Why this matters: This step separates real problems from imagined ones. A problem that only you experience is not a market. A problem that dozens of people independently describe across multiple platforms is a market.

What good looks like: You can link to 10+ pieces of evidence from at least 3 different platforms, written by different people, describing the same core problem.

Common mistake: Cherry-picking evidence. If you found 2 Reddit posts and 1 tweet after hours of searching, the problem might exist but it is not widespread enough. Be honest about the signal strength.

Step 3: Quantify the Pain

What to do: Determine how much time, money, or frustration the problem costs your target audience.

How to quantify:

  • Time cost: How many hours per week does someone spend dealing with this problem? Estimate from the evidence gathered in Step 2. If a recruiter spends 2 hours per day manually copying data from LinkedIn, that is 10 hours per week, or roughly $400/week at their hourly rate.
  • Money cost: Is the problem causing direct financial losses? Missed revenue, wasted ad spend, overpaying for services? Put a number on it.
  • Frustration cost: Sometimes the pain is not financial but emotional. Repetitive, boring tasks that drain motivation. These are harder to quantify but real. Look for language like "I dread doing this" or "this is the worst part of my job."

Why this matters: The size of the pain determines the price someone will pay for a solution. If the problem costs someone $50/month in wasted time, they will gladly pay $15/month to solve it. If the problem is a mild annoyance, they will not pay anything.

Tools: A simple calculation based on the target audience's hourly rate multiplied by hours wasted. Glassdoor or PayScale can provide salary data for specific job titles.

What good looks like: You can state: "This problem costs [target audience] approximately [X hours/dollars] per [week/month]." And you can back that number up with evidence.

Common mistake: Assuming the pain is greater than it is. Developers often overestimate how much non-developers care about efficiency. Just because a process seems inefficient to you does not mean the person doing it views it as a major problem.

Step 4: Measure Search Demand

What to do: Determine how many people actively search for a solution to this problem each month.

How to measure:

Tool What It Shows Cost
Google Ads Keyword Planner Exact monthly search volumes for specific keywords Free with Google Ads account
Google Autocomplete What people search for (directional, no volume data) Free
Google Trends Relative search interest over time and by region Free
NicheCheck Search volume + competitor data + revenue estimate combined Free tier available

Keywords to check:

  • "[Problem] tool"
  • "[Problem] software"
  • "[Problem] extension" (for Chrome extension ideas)
  • "Best [solution category]"
  • "How to [solve problem]"
  • "[Competitor name] alternative"

Why this matters: Search volume is the most direct measure of active demand. People who search for a solution are further along the intent spectrum than people who merely have a problem. They have recognized the problem and are actively looking for a fix.

What good looks like:

Monthly Search Volume Interpretation
Under 200 Very niche. Could work for high-ticket B2B but risky for consumer products.
200-1,000 Small but viable niche. Enough to build a micro-SaaS.
1,000-5,000 Solid niche. Strong enough to support a focused product.
5,000-20,000 Large niche. Multiple products can coexist.
Over 20,000 Mainstream market. Expect strong competition.

Common mistake: Only checking one keyword. A niche might not search for one specific phrase, but the combined volume of 10 related phrases could be significant. Also, some niches do not search because they do not know a solution could exist. Low search volume does not always mean low demand. Cross-reference with the evidence from Steps 2-3.

Step 5: Identify Your Target Customer

What to do: Create a specific profile of who your primary customer is.

What to define:

  • Job title or role: Not "anyone who uses Chrome" but "freelance web designers working solo"
  • Company size: Solo freelancer? 5-person startup? 500-person company?
  • Geographic focus: Global? US only? Specific regions?
  • Technical level: How comfortable are they with software? Will they need onboarding?
  • Budget authority: Can they purchase software themselves, or do they need approval?
  • Current tools: What do they use today to handle this problem?

Why this matters: Your target customer determines everything downstream: pricing, marketing channels, feature priorities, support expectations, and product design. A tool for enterprise IT managers has completely different requirements than one for indie hackers.

How to research:

  • Look at who is posting the complaints you found in Step 2. What are their job titles? Where do they work?
  • Check LinkedIn for the job titles you are targeting. How many people have that title?
  • Read the bios and profiles of people who review competing products on G2 or Capterra.

What good looks like: You can describe your customer specifically enough that you could find 100 of them on LinkedIn right now and send them a message they would find relevant.

Common mistake: Defining the customer too broadly because you want a bigger market. "Everyone who browses the internet" is not a customer segment. Start narrow. A product that is perfect for 500 people will grow faster than one that is mediocre for 50,000.

Step 6: Size the Market

What to do: Estimate how many people fit your target customer profile and how much revenue the market could generate.

Bottom-up method (preferred):

  1. Count how many people have the job title or fit the profile from Step 5 (LinkedIn is useful here)
  2. Estimate what percentage would adopt a paid tool (typically 5-20%)
  3. Multiply by your expected price (informed by competitor pricing)

Example calculation:

Factor Value
Freelance web designers in the US ~150,000 (from Bureau of Labor Statistics + LinkedIn data)
Percentage who work solo ~60% = 90,000
Percentage who would pay for a tool like this ~10% = 9,000
Monthly price $15
Annual addressable revenue 9,000 x $15 x 12 = $1.62M/year

Why this matters: Market sizing tells you the ceiling for your business. If the ceiling is $100K/year, this might be a great side project but not a full-time business. If the ceiling is $5M/year, it can support a serious company. Neither is inherently good or bad, but you need to know which one you are building.

What good looks like: Addressable annual revenue of at least $500K for a full-time business, or at least $100K for a side project.

Common mistake: Using top-down market sizing ("the project management software market is $6.6 billion, and we only need 0.001%"). This tells you nothing actionable. Always size bottom-up from identifiable individuals.

Step 7: Map the Competition

What to do: List every product that competes with your idea, directly or indirectly.

Types of competitors to find:

  • Direct competitors: Same problem, same audience, same solution type
  • Indirect competitors: Same problem, different solution approach (e.g., an agency that does manually what your tool automates)
  • Substitutes: Non-product alternatives (spreadsheets, manual processes, hiring someone)

For each competitor, record:

Data Point Source
Name and URL Web search
User count or customer base Product page, Chrome Web Store, review sites
Pricing Pricing page
Ratings and review count G2, Capterra, Chrome Web Store, Product Hunt
Last updated / Last feature release Blog, changelog, app store listing
Funding (if applicable) Crunchbase
Key features Product page, demo videos

Why this matters: Competition is the single most important factor in whether your product can gain traction. Understanding who you are up against and how strong they are determines your strategy.

Tools: Web search for most of this. For Chrome extension ideas, NicheCheck automates competitor discovery, pulling user counts, ratings, and update dates for any keyword.

What good looks like: A spreadsheet with 5-15 competitors, each with complete data. You understand the landscape well enough to explain it to someone who knows nothing about the space.

Common mistake: Only looking at direct competitors and ignoring substitutes. If your target audience currently solves the problem with a spreadsheet, that spreadsheet is your primary competitor, not the other SaaS tools in the space. You are competing with inertia.

Step 8: Analyze Competitor Weaknesses

What to do: For each competitor from Step 7, identify their top 3 weaknesses.

Where to find weaknesses:

  • 1-2 star reviews on G2, Capterra, Chrome Web Store, or Product Hunt. These are users telling you exactly what is wrong.
  • Feature request threads on the competitor's community forum or social media. These are users telling you what is missing.
  • Support forums and help docs. If the documentation is confusing or support tickets go unanswered, that is a weakness.
  • Try the product yourself. Sign up, use it for the intended use case, and note every friction point.

Categorize weaknesses:

Category Example Weakness
Functionality gap "It does X but not Y, and I need Y"
Usability problem "The interface is confusing and hard to learn"
Performance issue "It slows down my browser / takes too long to load"
Pricing complaint "Too expensive for what it offers"
Trust/privacy concern "Requests too many permissions" or "unclear data practices"
Support failure "Reported a bug 6 months ago, no response"
Stale development "Has not been updated in over a year"

Why this matters: Competitor weaknesses are your positioning opportunities. Each weakness you can address becomes a reason for users to choose your product instead.

What good looks like: You can articulate 3 specific, evidence-backed weaknesses for each major competitor, and at least 2 of those weaknesses are things you can credibly solve.

Common mistake: Assuming you can "just build a better version" without identifying what "better" specifically means. "Better" must be defined in terms the target customer cares about, which is what the weakness analysis reveals.

Step 9: Define Your Differentiation

What to do: Based on competitor weaknesses (Step 8) and customer needs (Steps 2-5), define exactly how your product will be different.

Differentiation must be:

  1. Meaningful to the target customer (not just technically interesting)
  2. Defensible over time (not easily copied by competitors)
  3. Communicable in one sentence (if you cannot explain it simply, it is not clear enough)

Differentiation types:

Type Example Defensibility
Better UX for a specific workflow "Designed specifically for recruiters, not generic HR" Moderate - requires domain expertise to replicate
Privacy/security advantage "No data leaves your browser, ever" High - architectural decision that is hard to retrofit
Price disruption "Same features at 1/3 the price" Low - competitors can match your price
Integration advantage "Works natively with [specific tool your audience uses]" Moderate - integration work takes time
Audience specialization "Built for pet groomers, not generic scheduling" High - requires understanding a niche competitor might ignore

Why this matters: Without clear differentiation, you are asking users to switch from a known product to an unknown one for no specific reason. Most people will not do that. You need a concrete "why you, not them" answer.

What good looks like: "Unlike [competitor], we [specific difference] which means [specific benefit for the customer]." And you have evidence from Steps 2-8 that the customer cares about that specific benefit.

Common mistake: Defining differentiation as "we do everything they do, but better." That is not differentiation. That is hubris. Pick 1-3 specific dimensions where you will be meaningfully better and accept that competitors may be better on other dimensions.

Step 10: Validate Willingness to Pay

What to do: Determine whether your target audience will actually pay for a solution.

Willingness-to-pay signals:

Signal Strength
People already pay for competing products Very strong
People describe the problem in dollar terms ("costs me $X per month") Strong
People have tried free solutions and express frustration with limitations Moderate
People describe the problem as time-consuming but have not tried to solve it Weak
People acknowledge the problem but describe it as minor Very weak

Direct validation methods:

  • Survey your target audience. Use the Van Westendorp Price Sensitivity Meter: ask what price would be "too cheap" (suspicious), "a bargain," "getting expensive," and "too expensive." The intersection of these curves gives you the optimal price range.
  • Pre-sell the product. Create a landing page describing your solution and offer a founding member discount. If people pay before the product exists, you have validated willingness to pay at the strongest possible level.
  • Analyze competitor pricing. If competitors charge $10-50/month and have thousands of paying users, the market supports those price points.

Why this matters: A real problem does not always mean a paying customer. Some problems are painful but not worth paying to solve. Others are painful and people will gladly pay. You need to know which situation you are in.

What good looks like: At least one of these is true: (a) competitors have paying customers at a price point similar to yours, (b) 10+ target customers told you a specific price they would pay, or (c) 5+ people pre-purchased your product.

Common mistake: Asking "would you pay for this?" and trusting the answer. Hypothetical willingness to pay is nearly meaningless. People say yes to be polite. The only reliable signal is actual payment or behavior that strongly implies payment intent (like signing up for a free trial and using it extensively).

Step 11: Estimate Revenue Potential

What to do: Build a realistic revenue model based on the data you have gathered.

Inputs you need:

Input Source
Total addressable users Step 6 (market sizing)
Expected conversion rate to free/trial Industry benchmarks: 2-10% of aware users
Expected conversion from free to paid Industry benchmarks: 2-5% for freemium, 10-25% for free trials
Monthly price Step 10 (willingness to pay)
Monthly churn rate Industry benchmark: 3-7% for SMB SaaS

Simple revenue model:

Assume you can reach 10% of your addressable market within 2 years. Of those, assume 3% convert to paid (freemium) or 15% convert (free trial). Apply monthly churn to get steady-state customers.

Example:

Factor Value
Addressable market 9,000 potential users
Reached in Year 2 10% = 900
Conversion to paid (freemium) 3% = 27 paying customers
Monthly price $25
Monthly churn 5%
Steady-state MRR ~$675 (modest)

If those numbers look too low, either the market is too small, the price is too low, or you need a different acquisition model. Adjust assumptions and see what must be true for the business to reach your target revenue.

Tools: A spreadsheet is sufficient. For automated estimates based on real competitor data, use the NicheCheck revenue estimator.

Why this matters: Revenue modeling forces you to confront reality. Many ideas sound great until you run the numbers and realize the market cannot support a full-time income at realistic conversion rates.

What good looks like: Your model shows a path to at least $5K MRR within 18 months with conservative assumptions. If it requires heroic assumptions (50% conversion rates, zero churn), the economics do not work.

Common mistake: Using optimistic assumptions at every stage. Each optimistic assumption multiplies the others. If you are optimistic about market size, conversion rate, AND churn rate, your projections will be wildly inflated. Use conservative assumptions and see if the business still works.

Step 12: Identify Distribution Channels

What to do: Determine how you will get your product in front of your target customers.

Common distribution channels for niche products:

Channel Best For Cost Timeline
SEO/Content marketing Products with search demand (Step 4) Low ($) Slow (6-12 months to see results)
Chrome Web Store organic Chrome extensions Free Medium (3-6 months)
Product Hunt launch Developer and tech-savvy audiences Free Fast (but one-time spike)
Reddit/community engagement Niche audiences in specific subreddits Free Medium
Cold outreach (email/LinkedIn) B2B products with identifiable buyers Low Medium
Paid ads (Google/Facebook) Products with strong search intent High ($$) Fast
Partnerships/integrations Products that complement existing tools Low Slow
Word of mouth Products with strong viral loops Free Slow but compounding

Why this matters: The best product in the world fails without distribution. You need at least 2 viable channels that can deliver customers sustainably, not just at launch.

How to evaluate each channel:

  1. Can you reach 1,000 target customers through this channel? (minimum viable scale)
  2. Can you afford the customer acquisition cost? (CAC must be less than 1/3 of LTV)
  3. Can you sustain this channel long-term? (paid ads require ongoing budget; SEO requires ongoing content)

What good looks like: You have identified at least 2 channels where: you can reach your target audience, the economics work, and you have the skills or resources to execute.

Common mistake: Planning to "go viral" or "get featured on TechCrunch" as your distribution strategy. These are one-time events, not sustainable channels. Even if they happen, you need a plan for the other 364 days of the year.

Step 13: Test Your Positioning

What to do: Create a landing page or one-pager that describes your product and put it in front of your target audience. Measure whether they engage.

What to test:

Element What You Are Testing
Headline Does the problem statement resonate?
Value proposition Does the solution description create interest?
Call-to-action conversion rate Are people willing to take the next step (email signup, waitlist)?
Bounce rate Are the right people landing on the page?
Time on page Are they reading or immediately leaving?

How to drive traffic:

  • Post in 2-3 relevant communities (Reddit, LinkedIn groups, Slack communities) with a genuine description of what you are building and a link. Not a spammy promotion, but a "I'm building X, curious if this is useful to anyone" post.
  • Run $50-100 in Google Ads targeting your primary keywords from Step 4.
  • Share with the people you interviewed in earlier steps.

Why this matters: Positioning is how your product is perceived by the market. Getting it right determines whether people click, sign up, and eventually pay. Testing positioning is cheap. Building the wrong product is expensive.

Conversion benchmarks:

Metric Minimum Viable Good
Visitor to email signup 3% 8%+
Visitor to waitlist 2% 5%+
Bounce rate Under 70% Under 50%
Average time on page Over 30 seconds Over 60 seconds

What good looks like: At least 5% of targeted visitors (not random traffic) take your desired action.

Common mistake: Driving untargeted traffic (posting in a general startup subreddit) and then being surprised by low conversion. The test is only valid if the traffic matches your target audience from Step 5.

Step 14: Assess Technical Feasibility

What to do: Confirm that you can actually build the product within your constraints (time, budget, skills, platform limitations).

Key questions:

  1. Can this be built with technologies I know? If you need to learn an entirely new stack, add 2-3 months to your timeline. Is that acceptable?

  2. Are there hard technical constraints? For Chrome extensions: can this work within Manifest V3 limitations? For web apps: are the APIs you need available and affordable? For AI-powered features: what will the API costs be at scale?

  3. What is the realistic timeline to MVP? An MVP should take 2-8 weeks, not 6 months. If your idea requires 6 months of development before anyone can use it, you are building too much.

  4. Can I maintain this solo? Ongoing maintenance includes bug fixes, security updates, customer support, and adapting to platform changes. Estimate 5-10 hours per week for a mature product.

  5. What are the dependencies? If your product relies on a third-party API (LinkedIn, Chrome Web Store, a social media platform), that dependency is a risk. APIs change, rate limits tighten, and access can be revoked.

Why this matters: The most validated idea in the world is useless if you cannot build it. Technical feasibility is the pragmatic counterpart to market validation.

What good looks like: You can build an MVP in 4-8 weeks with your current skills, the technology stack is mature and well-documented, and you have no critical single-point-of-failure dependencies.

Common mistake: Underestimating the ongoing maintenance burden. Building is the easy part. Maintaining a product through Chrome updates, API changes, customer support requests, and security patches is the hard part. Make sure you are signing up for the long-term commitment, not just the initial build.

Step 15: Make the Go/No-Go Decision

What to do: Review your results from Steps 1-14 and make a deliberate, evidence-based decision.

The scoring framework:

Rate each step as Pass, Marginal, or Fail:

Step Result Score
1. Niche definition Clear and specific? Pass/Marginal/Fail
2. Problem evidence 10+ independent sources? Pass/Marginal/Fail
3. Pain quantification Measurable time/money cost? Pass/Marginal/Fail
4. Search demand 500+ monthly searches? Pass/Marginal/Fail
5. Target customer Specific and identifiable? Pass/Marginal/Fail
6. Market size $500K+ addressable revenue? Pass/Marginal/Fail
7. Competition mapped Complete landscape documented? Pass/Marginal/Fail
8. Competitor weaknesses Specific, actionable gaps found? Pass/Marginal/Fail
9. Differentiation Clear, meaningful, communicable? Pass/Marginal/Fail
10. Willingness to pay Evidence of payment behavior? Pass/Marginal/Fail
11. Revenue model Path to $5K MRR in 18 months? Pass/Marginal/Fail
12. Distribution channels 2+ viable channels identified? Pass/Marginal/Fail
13. Positioning tested 5%+ conversion from targeted traffic? Pass/Marginal/Fail
14. Technical feasibility MVP in 4-8 weeks? Pass/Marginal/Fail

Decision criteria:

Result Action
12+ Pass, 0 Fail Strong go. Build with confidence.
10-11 Pass, 0-1 Fail Conditional go. Address marginal areas during development.
8-9 Pass, 1-2 Fail Pivot. Adjust the idea to address failing areas, then re-validate.
Under 8 Pass or 3+ Fail Kill the idea. Move on to the next one.

Why this matters: The purpose of the checklist is to make the decision explicit and evidence-based, not emotional. Killing a validated-bad idea is a success, not a failure. You just saved months of wasted development time.

What good looks like: You can present your checklist to a skeptical friend and defend every rating with specific evidence.

Common mistake: Being emotionally attached to the idea and overriding the checklist results. If 6 of your 15 steps came back negative, the idea is not ready. Either improve it or drop it. Do not rationalize your way past the evidence.

Putting the Checklist Into Practice

Timeline

This entire checklist can be completed in 1-2 weeks of focused work. Here is a suggested timeline:

Days Steps Activities
Day 1-2 Steps 1-3 Define niche, gather problem evidence, quantify pain
Day 3-4 Steps 4-6 Measure search demand, define customer, size market
Day 5-7 Steps 7-9 Map competition, analyze weaknesses, define differentiation
Day 8-9 Steps 10-11 Validate willingness to pay, build revenue model
Day 10-12 Steps 12-14 Identify channels, test positioning, assess feasibility
Day 13-14 Step 15 Score checklist, make decision

Automating Parts of the Checklist

Several steps can be partially automated:

  • Steps 4, 7, and 11 (search demand, competition mapping, and revenue estimation) can be handled by NicheCheck. Enter your keyword, and get search volume data, a complete competitor landscape, and revenue projections in minutes.
  • Step 11 specifically benefits from the revenue estimator, which models income potential based on real competitor user counts rather than guesswork.

What If You Are Validating Multiple Ideas?

Run Steps 1-4 on all your ideas first. These steps are fast and will eliminate most candidates. Then run the full checklist only on the 1-2 ideas that survive the initial filter. This prevents you from spending two weeks validating an idea that could have been eliminated in two hours.

Keeping a Validation Journal

Document your validation process as you go. For each step, write down: - What evidence you found - What surprised you - What your honest assessment is (Pass/Marginal/Fail)

This journal serves two purposes: it forces you to be rigorous during the process, and it gives you a reference document if you want to revisit the idea later.

Frequently Asked Questions

"What if my idea is truly novel and has no competitors?"

Go back to Step 2 and look harder. If you truly have zero competitors and zero substitutes, the most likely explanation is that the market does not exist. Occasionally a genuinely novel idea comes along, but it is rare. Usually, "no competitors" means "I did not search hard enough" or "others tried this and it failed."

"How much money should I spend on validation?"

$0-300 is typical. The most expensive part is usually running a small Google Ads campaign to test positioning (Step 13). Everything else can be done with free tools and manual research. Do not spend thousands of dollars validating. That is building, not validating.

"Can I validate while building?"

Partially, yes. Many developers start building an MVP while simultaneously running the validation checklist. The key is to not invest more than 2 weeks of building until you have completed at least Steps 1-9. If those steps fail, you have lost 2 weeks instead of 6 months.

"My validation results are mixed. Now what?"

Mixed results are normal. The question is where the failures are. Failing on market size but passing everything else might mean you have a viable niche product (good for a side project, not for a full-time venture). Failing on competition but passing on demand might mean you need a stronger differentiation angle. Use the specific failure points to iterate on the idea rather than abandoning it entirely.

"Do I need to do all 15 steps?"

For a serious business, yes. For a weekend side project, Steps 1-4 and 7 (niche definition, problem evidence, pain quantification, search demand, and competition mapping) are the minimum. These five steps take one to two days and will prevent you from building something completely misguided.

Conclusion

Most products fail not because they are poorly built, but because they are built for a market that does not exist, does not pay, or is already saturated. This checklist exists to catch those failures before they cost you months of development time.

Every hour you spend on validation saves 10-20 hours of building the wrong thing. That is not a poetic exaggeration. It is a practical reality that experienced founders have learned the hard way.

Start your validation today:

The best time to validate was before you had the idea. The second-best time is right now, before you open your code editor.
