Don’t hire people just to fit the first job they will do; hire people you want to share your life with.

To be effective you must not let your need to be right be more important than your need to find out what’s true. If you are too proud of what you know or of how good you are at something you will learn less, make inferior decisions, and fall short of your potential.

Remember that everyone has opinions and they are often bad. Opinions are easy to produce; everyone has plenty of them and most people are eager to share them—even to fight for them. Unfortunately many are worthless or even harmful, including a lot of your own.

Every time you confront something painful, you are at a potentially important juncture in your life—you have the opportunity to choose healthy and painful truth or unhealthy but comfortable delusion.

Look for people who have lots of great questions. Smart people are the ones who ask the most thoughtful questions, as opposed to thinking they have all the answers. Great questions are a much better indicator of future success than great answers.

If you can’t successfully do something, don’t think you can tell others how it should be done

Thoughtful disagreement is not a battle; its goal is not to convince the other party that he or she is wrong and you are right, but to find out what is true and what to do about it.

Any damn fool can make it complex. It takes a genius to make it simple

Remember that the only purpose of money is to get you what you want, so think hard about what you value and put it above money. How much would you sell a good relationship for? There’s not enough money in the world to get you to part with a valued relationship.
