🔮 Life Decision 5-Scenario Forecaster
Five realistic 10-year futures for any major decision — with probabilities, tradeoffs, and the question you should actually be asking.
Why this is epic
Most AI gives you generic pros/cons lists. This gives you five genuinely different probable futures — each with realistic setbacks, specific financial impact, and the identity-level shift you'd undergo.
Forces you to see the decision underneath the decision. The counterintuitive insights per scenario are usually what tips the real choice.
Anti-optimism-bias baked in. No 'follow your dreams' platitudes — includes the scenarios where things go sideways with the same rigor as where they work.
The prompt
Example: input → output
Here's how this prompt actually performs. Real input below, real output from Claude Opus 4.
The decision: Should I leave my stable $120k senior software engineer job at a mid-size SaaS company to start a bootstrapped B2B SaaS? Context: I'm 34, married 5 years, no kids yet but we want them within 3 years. $80k savings, no debt. Partner works part-time ($40k/yr) and supports the idea but is risk-averse. I have 12 years of experience, a specific problem in mind (dev tooling), and 3 potential co-founders. What matters most (1-5): creative fulfillment, financial security, relationship stability, health, growth. Anti-leverage: I've never founded before. I have no customers yet, just the idea. If I fail, re-entering at my current level might be hard at 36 with a gap on the resume.
5 Realistic 10-Year Scenarios
Scenario A: Slow Burn to Acquisition — 28% probability
The arc: You leave the job at month 3, spend 18 months building with one of the three co-founders. Revenue ramps slowly — $2k MRR at year 1, $40k MRR at year 3. A mid-tier public SaaS acquires you for $4-8M at year 5. You stay as VP of Engineering for the acquirer for 2-3 years, then retire from corporate work at 42.
- Year 1–2: Burn through $60k of savings. Two co-founders drop out by month 14. Partner starts full-time work again. Marriage has its first real fight about money — survives.
- Year 3–5: First enterprise deal at $80k ARR validates the product. Hire 3 people. Acquisition conversation starts at year 4.5 after you attend an industry event.
- Year 6–10: Post-acquisition golden handcuffs. You quietly start angel investing. Kids arrive at year 6 as planned.
Financial: $4-8M liquidity event year 5. After taxes and paying co-founder: $2-4M net. Continued $200k salary for 2 years at acquirer. Lifetime: significantly better than staying.
Relationships: Marriage stronger after the crisis at year 2. Partner goes back to work she loves by year 4.
Health & Energy: Worst between months 12-24. Back to baseline by year 4. Year 6+ is the healthiest decade of your life.
Identity shift: From "senior engineer" to "operator". At 44, you describe yourself as "a builder who got lucky and is careful about what to do next".
Counterintuitive insight: The acquisition was only possible BECAUSE you grew slowly. Had you raised VC money, you'd have been forced to grow faster, miss product-market fit, and burn out before the acquirer noticed.
Scenario B: Flame Out, Return Stronger — 24% probability
The arc: You build for 16 months. Revenue never breaks $8k MRR. You shut it down in month 20 with $15k left in savings. You return to employment at a peer-tier company — but as a Staff Engineer, because the founding experience actually helped your skills. You're back at $140k within 3 months, $180k by year 3, $220k by year 5.
- Year 1–2: Product works technically but no wedge. Partner carries household fully. Stress.
- Year 3–5: Back at full-time job. The founding story becomes interview gold. Promoted to Staff Engineer at year 3, then Principal at a new job at year 4.
- Year 6–10: Kids arrive year 4. Comfortable upper-middle-class stability. Occasional "what if" moments but no deep regret.
Financial: -$60k net over 18 months, recovered by year 3. Lifetime: roughly neutral to current path, maybe +$100-200k.
Relationships: Partner's resentment spike in months 14-18 is real. Takes 6-12 months to fully recover trust.
Health & Energy: Sleep debt from the 18-month push takes 12 months to recover. Watch for back issues from stress-eating.
Identity shift: From "someone with no battle scars" to "someone who tried". Quietly confident in a way your current self isn't.
Counterintuitive insight: The 18 months you'd call a "failure" will be the defining credential of your career. It gets you into rooms that stable employment never would.
Scenario C: The Trap That Looks Like Success — 18% probability
The arc: You hit product-market fit at month 14. Revenue goes to $50k MRR fast. You hire 5 people. But growth plateaus at $80k MRR and won't budge. You spend years 3-8 running a "fine" business that demands 60+ hours/week and isn't getting bigger. You're too successful to quit, too small to matter.
- Year 1–2: Euphoric. This is the dream.
- Year 3–5: Kids arrive year 3. You're absent for months 18-36 of their lives in a way you don't fully see until year 6.
- Year 6–10: You sell at year 8 for $2M and feel relief, not pride. The $2M is less than you'd have earned staying employed with equity grants.
Financial: $2M sale year 8. Net: roughly $300-600k BETTER than employment over 10 years, but you lost hundreds of evenings.
Relationships: Marriage OK but starved. You miss your children's early years in a way that hurts at year 10.
Health & Energy: Weight gain. Back pain. First mental-health prescription by year 5.
Identity shift: From "engineer" to "manager who misses engineering". At 44 you describe yourself as "tired" before anything else.
Counterintuitive insight: This is the "successful" path everyone warns you about but few founders recognize they're on until year 4. The question isn't will you succeed — it's whether the success will look like what you wanted.
Scenario D: The Pivot That Works — 18% probability
The arc: Initial product fails at month 8. You pivot to an adjacent problem you noticed while building. That idea hits — different market, different pricing, different everything. By year 4 you're running a $2M ARR vertical-SaaS company. Stable, not hyper-growth, but dominant in its niche.
- Year 1–2: Rough. Original co-founders leave. You nearly quit at month 9 before the pivot insight lands.
- Year 3–5: First baby born year 3. You hire well and delegate well — the 18-month solo struggle forced you to become the operator the business needed.
- Year 6–10: Business throws off $400k/year to founders. You work 30 hours/week from year 6 onward. Kids see you constantly.
Financial: $300-500k/year from year 5 onward. Net over 10 years: roughly +$1-2M vs. employment.
Relationships: Marriage is better than it would have been otherwise — the early struggle taught you both how to fight well.
Health & Energy: Strong. The 30-hour work week from year 6 is what the 60-hour employment track never offered.
Identity shift: From "engineer" to "founder-operator". At 44, you describe yourself as someone who built something useful and has time.
Counterintuitive insight: The pivot that saved you was only visible from INSIDE the failing original. Had you stayed employed and "researched markets" from outside, you'd have never seen it.
Scenario E: Ghost Year, Return Same — 12% probability
The arc: You try for 8 months. You can't build momentum. Partner pregnancy accelerates your return to employment. You spin it as a "sabbatical" on your resume. You're back at $125k at a similar company within 4 months. Life continues essentially unchanged — you kept the idea, not the risk.
- Year 1–2: Short detour. No lasting damage.
- Year 3–5: Kids, mortgage, career trajectory identical to the non-decision scenario.
- Year 6–10: Normal life. Every 2-3 years you think "maybe I'll try again". You don't.
Financial: -$30k over 8 months, recovered by year 2. Lifetime: essentially identical to staying employed.
Relationships: Unaffected.
Health & Energy: Unaffected.
Identity shift: Minimal. You tell yourself the story that you tried, but a quiet part of you knows you didn't really.
Counterintuitive insight: This is the worst outcome of the five, financially and otherwise equivalent to staying — but with a lasting "I tried and it didn't work" belief that blocks future risks. Better to stay and not try than to do this half-version.
Meta-Observation
The real question isn't "should I start a company" — it's "do I want to live the next 2 years of my life as a worker or as a founder". The 10-year financial outcome across scenarios A-D is broadly similar (±$500k on $2M+). What changes is WHO you are and the texture of those 24 months. Scenario E is the only losing bet because it's an identity half-measure.
The Question You Should Actually Ask Yourself
If you knew with 100% certainty you'd fail and be employed again by month 20, would you still do it?
If yes: go. The value is in the 20 months, not the outcome.
If no: stay. Your motivation is the outcome, which means you'll optimize for it in ways that make failure more likely, not less.
Common use cases
- Quitting a stable job to start a company
- Whether to move cities or countries
- Relationship decisions (commit / leave / reset)
- Career pivots and specialization choices
- Financial decisions: house, kids, education
Best AI model for this
Claude Opus 4 (deepest reasoning; best for judgment-heavy scenarios). ChatGPT GPT-5 Pro is second-best.
Pro tips
- Rank your top-5 values BEFORE running. The prompt forces honesty — if 'security' beats 'growth', scenarios change dramatically.
- Include your anti-leverage (what weakens your position). Most users over-state their options. The prompt works best with honest constraints.
- Run it twice, 24 hours apart, with slightly different framings of the same decision. Compare outputs — the robust insights repeat.
Customization tips
- Replace the decision with any major life fork — career, relationship, relocation, financial.
- Be ruthlessly honest about your values ranking. If 'security' actually beats 'growth' but you write the reverse, the scenarios will be useless.
- Include real numbers: salary, savings, runway. The prompt uses them for realistic financial projections.
- Anti-leverage is critical. Most users over-state their options. Be honest about what weakens your hand.
