As I was getting interviewed by the Wall Street Journal, or some big pub guy, all I remember was that he went off to the bathroom for a second, and they brought out my omelet. The next thing I remember, I woke up, and I was on the side of my own omelet, and there was no one at Buck's. Everyone was gone. They just let me sleep.

The very first company I started failed with a great bang. The second one failed a little bit less, but still failed. The third one, you know, proper failed, but it was kind of okay. I recovered quickly. Number four almost didn't fail. It still didn't really feel great, but it did okay. Number five was PayPal.

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.

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.

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

Right now, nearly all the apps on Facebook take a week to build. No more.

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.
