You can have successful teams where people hate but deeply respect each other; the opposite (love but not respect among team members) is a recipe for disaster.

PayPal once rejected a candidate who aced all the engineering tests because for fun, the guy said that he liked to play hoops. That single sentence lost him the job.

Being an entrepreneur is not about being in love with an idea, it's about being in love with running a company.

Ignore your mistakes. The number one thing to worry about is -Am I doing what I'm good at?

I have this massive notebook called IDEAS and another one called PERSONAL IDEAS and another one called CRAZY IDEAS.

I think the hallmark of a really good entrepreneur is that you're not really going to build one specific company. The goal - at least the way I think about entrepreneurship - is you realize one day that you can't really work for anyone else. You have to start your own thing. It almost doesn't matter what that thing is.
