Charlie Munger describes how he has used mental models in his life to achieve great success. He talks about inversion, Occam’s razor, and more.
- Start with the problem rather than working backwards from the goal.
- Don’t think about what you want, think about what you want to avoid.
- Example Munger gives was he was a meteorologist; he was tasked to predict the weather. His goal was to clear pilots for takeoff. He looked at it as his job was to prevent killing the pilots, and the pilots can be killed by icing or if they ran out of fuel.
- For stocks, instead of looking for ways to gain lots of money, look for how you could lose a lot of money.
