You can hear it in every playground: “Why? … But why?” Kids are natural detectives. Adults, on the other hand, often trade curiosity for certainty. The shift from kid to adult isn’t about losing “why,” it’s about learning “how to think.”
Think of it like upgrading from reacting to life to running your own operating system. You don’t just take inputs. You process, test, and decide. Below is a simple, practical playbook—peppered with stories and metaphors—to help you build that OS. Style-wise, imagine if James Clear and Morgan Housel sat down over coffee to write a field guide ☕️
- Ask better questions
Flashlight vs. floodlight. “Why?” is a flashlight—it helps, but it can get narrow. Better questions are a floodlight.
Try these:
- What am I missing?
- What would change my mind?
- What evidence would prove the opposite?
- Who is this for, and what does success look like?
- What are the second-order effects?
Example: You’re choosing a marketing channel. Instead of “Why TikTok?”, ask “What metric proves this works within 30 days?” and “What would make me kill it fast?” Now you’re evaluating, not just rationalizing.
Tool: The 5 Whys. Ask “why” up to five times until you hit a root cause. It’s like peeling an onion 🧅—tears sometimes included.
- Slow down and map the problem
Don’t sail without a map. A one-page brief is your nautical chart.
Make one page:
- Context (3 sentences)
- Goal (1 sentence, measurable)
- Constraints (time, money, people)
- Options (3–5)
- Top risks for each option
- Decision date and owner
Example: Hiring a salesperson
- Goal: Close $60k new MRR in 6 months
- Constraint: $8k/month budget
- Options: Senior hire, junior + training, outsource agency
- Risks: Ramp time, quality, brand control
- Decision date: Sept 15; Owner: You
If it doesn’t fit on one page, you don’t understand it yet.
- Break decisions into small bets
Don’t jump the canyon—build stepping stones.
Turn binary choices into stages:
- Pilot Stage → Expand → Standardize
Example: Considering a new CRM?
- Pilot: 2-week trial, 1 team, $0–$500 cost
- Target: Time-to-quote under 2 minutes, data accuracy 98%
- Rules: If targets hit, expand in 30 days; if not, revert. No sunk-cost loyalty.
- Write before you consult
Fog clears when you write. Your thoughts condense into shape ✍️
Use a 10-minute memo:
- Hypothesis
- Evidence (links/data)
- Alternatives considered
- Risks/unknowns
- Next step decision
Example:
– Hypothesis: We can drop CAC 25% by switching to creative A/B weekly.
– Evidence: last 3 tests.
– Risk: fatigue.
– Decision: 4-week sprint with pre-set kill rules.
- Run simple experiments
Kitchen science. Change one ingredient, taste, repeat 👩🍳
Make it testable:
- If we change X, we expect Y by Z date.
Example: Pricing test
- If we move from $49 to $59, we expect revenue per user +10% with churn < 1.5% monthly by end of the quarter.
- One variable at a time. No moving goalposts.
- Set decision rules up front
Guardrails on a mountain road. You can move fast because you know where not to go 🛣️
- Threshold rules:
- Ship if beta NPS > 45
- Kill if CAC:LTV > 2:1 after 30 days
- Guardrails:
- Budget cap, time cap, quality bar
- Escalation:
- What the team can do vs. what needs your approval
Example: Content program
- Spend $3k/month for 90 days
- Success: Organic leads ≥ 30/month, SQL%, and close rate steady
- If fail, pivot to paid + partnerships
- Do premortems and postmortems
Read the last chapter first. Imagine it failed—why? Then make that less likely 📉
Premortem: “It’s six months later. This flopped because…”
- Reason 1: Wrong audience
- Reason 2: Poor onboarding
- Reason 3: Underpriced, churn rose Mitigate top two now.
Postmortem:
- What did we expect?
- What happened?
- Why the gap?
- What will we change next time?
Capture in a decision log. Progress compounds when lessons do.
- Track your judgments like a KPI
Calibrating a compass. If it’s off by 5 degrees, you miss the island 🧭
Decision Journal fields:
- Decision, alternatives
- Confidence % (be honest)
- Expected outcome & by when
- Rationale
- Review date
- Result & lesson
Quarterly, check your calibration. If you’re 90% confident but only right 60%, you’re overconfident. Dial it down.
- Build a small “board of advisors”
Your personal Justice League 🦸
- 5–7 folks across product, finance, legal, brand, hiring
- Send crisp memos; ask for red flags, not generic advice
- Offer value back: intros, beta access, your expertise
Example text: “2-min read. Goal: reduce churn 20% in Q4. Options A/B/C. Any red flags or blind spots you see?”
- Sleep on big calls
Let the snow globe settle. Clarity shows up after stillness ❄️
Use reversibility:
- High impact, reversible: decide fast.
- High impact, hard to reverse: get dissenting opinions and sleep on it.
Often, the next morning gives you the one insight you were missing.

Two quick stories
- The $1,000 ad test: A founder I know stopped debating channels and ran four $250 ad pilots in two weeks. One channel hit CPA $42 with solid lead quality; the others failed fast. He scaled the winner 10x the next month and doubled revenue in a quarter. Debate turned into data.
- The product “no” that saved the quarter: A team wanted a flashy feature. The premortem surfaced a risk: it would slow onboarding by 30%. They added a guardrail—onboarding time must not exceed 7 minutes in beta. The feature missed the bar, they killed it, and focused on speed. Churn dropped.
Closing thought
Kids ask “why” to find the world’s edges. Adults learn “how to think” to redraw those edges with intention. Keep the kid’s curiosity. Add the adult’s process. That’s how you make better calls, faster, with less regret.
