Finding "how to guarantee failure" in order to reverse-engineer "how to guarantee success"
Core Concept
Flip the question. Instead of "how do I succeed?", ask "how do I guarantee failure?" List every way to ruin this — then avoid them. Munger: "Tell me where I'm going to die, so I'll never go there."
✓ When to use this
When stuck on "how do I succeed," flipping to "how do I guarantee failure" is often easier to answer. Great for strategy review too — avoiding obvious disasters is more reliable than chasing the optimal path.
✗ When not to use this
Skip pure creative ideation (art, product imagination) — inversion pulls focus back to avoiding mistakes and kills exploration. In the optimistic brainstorming phase, let positive ideas grow first.
Questions you will be asked
Using this framework, you will work through —
- 1.What is your goal?
- 2.Now invert it: how would you guarantee this fails completely?
- 3.Which items from your failure list are you currently doing?
- …and 3 more
