We [Facebook] really believe in enabling people to be their authentic selves on the web, and enabling people to communicate directly with each other in a very personal way.

When we get feedback on women, we ask, "Is that real or is that the gender bias at play?" Everyone could start doing that today and I think we'd see really big results.

Your life's course will not be determined by doing the things that you are certain you can do. Those are the easy things. It will be determined by whether you try the things that are hard.

Speak up. Believe in yourself. Take risks.

Fortune does favor the bold and you'll never know what you're capable of if you don't try.

If I had to embrace a definition of success, it would be that success is making the best choices we can ... and accepting them.

When looking for a life partner, my advice to women is date all of them: the bad boys, the cool boys, the commitment-phobic boys, the crazy boys. But do not marry them. The things that make the bad boys sexy do not make them good husbands. When it comes time to settle down, find someone who wants an equal partner. Someone who thinks women should be smart, opinionated and ambitious. Someone who values fairness and expects or, even better, wants to do his share in the home. These men exist and, trust me, over time, nothing is sexier.
