9 Mental Models that will level up your Thinking:
1. Map vs. Territory - Theory has its limits. Don't rely on step-by-step instructions. Learn theory, apply it, and readjust.
2. Second-Order Thinking - Instead of thinking about the immediate consequences, think about the second-level consequences.
3. The Precautionary Principle - Precaution is better than cure.
— Johann Wolfgang von Goethe
4. Asymmetric Bets - Put yourself in situations with limited downside and unlimited upside
5. Cause-Effect Fallacies - Keep in mind that there aren't always cause-effect relationships. Lots of stuff is random.
6. Margin of Safety - Assume that your assumptions can be wrong and plan with a safety margin.
7. Occam's Razor - Always start with the simplest explanation, the one based on the least assumptions.
Then move to the other explanations if wrong.
8. Dedication - Commit to a simple idea and take it seriously.
9. Inversion - Approach problems backward.
Don't ask: "What do I need to do?" Ask: "What must I avoid?"
