I focus on things that are the highest value and do them perfectly.

Facebook is such a basic utility. It's something that is such a part of peoples' lives, I think it's hard to imagine it going away.

You actually don't want people thinking your product is cool, because then you're a fad.

I lived on couches for something like six months. I had no home. I was totally broke. I would stay at a friend's house for two weeks, then move because I didn't want to become this permanent mooch.

If I were worried about my reputation, I wouldn't do anything with start-ups

At every point I am besieged by people who would like me to conform to some social norm of whatever sort of social group they expect me to be a part of. I never have any identification with these social groups.

One of the difficulties in living the lifestyle I lead is that it is hard to get my friends in one place.
