12 key ideas across 2 books, each explained in our own words.
Clear Thinking
- IDEA 1
Defaults drive decisions
Most bad decisions come from automatic reactions like ego, emotion or social pressure. Create space before reacting so you can choose.
- IDEA 2
Strengthen your defaults
Build habits and environments that make good choices automatic, so you need less willpower in the moment.
- IDEA 3
Own the outcome
Self-accountability means not blaming circumstances. Ask what you could have done differently.
The Great Mental Models
- IDEA 1
The map is not the territory
Models simplify reality and can mislead. Check whether your map still matches the ground.
- IDEA 2
Circle of competence
Know what you understand deeply and what you don't. Make big bets only inside your circle.
- IDEA 3
First principles
Break a problem down to basic truths, then rebuild solutions from there instead of copying others.
