When to use it
Use it for big, hard-to-reverse career decisions.
How to apply it
- Describe the decision and the options clearly.
- Imagine yourself at 80 looking back.
- Ask which option you would regret not trying.
- Separate short-term discomfort from long-term regret.
- Decide, and set a review point to check how it is going.
Tip: It is a tie-breaker for values, not a substitute for checking finances and risks.
