Great CEOs are not just born with shiny hair and a tie.

We have never lived in a time with the opportunity to put a computer in the pocket of 5 billion people.

If you think you can execute a previously failed idea, you just have to be able to show that now is the time.

People are so bad at driving cars that computers don't have to be that good to be much better. Any time you stand in line at the D.M.V. and look around, you're like, 'Oh, my God, I wish all these people were replaced by computer drivers.'

I don't think objectively we are in a tech bubble when tech stocks are at a 30 year low.

I hope to someday live in a world where there are lots more Silicon Valleys.

It was a joke, okay? If we thought it would actually be used, we wouldn't have written it!
