People wait until late in their career to give back. But why wait when there is so much to be done?

I’m here to build something for the long-term. Anything else is a distraction.

I know it sounds corny, but I’d love to improve people’s lives, especially socially… Making the world more open is not an overnight thing. It’s a ten-to-fifteen-year thing.

A guy who makes a new chair doesn't owe money to everyone who ever built a chair.

I think that more flow of information, the ability to stay connected to more people makes people more effective as people. And I mean, that's true socially. It makes you have more fun, right. It feels better to be more connected to all these people. You have a richer life.

If we want to have the biggest impact, the best way to do this is to make sure we always focus on solving the most important problems.

It only took me two weeks to build the first version of Facebook because I had so much stuff before then.
