Helping a billion people connect is amazing, humbling and by far the thing I am most proud of in my life.

I do everything on my phone as a lot of people do.

You can be so bad at so many things... and as long as you stay focused on how you're providing value to your users and customers, and you have something that is unique and valuable... you get through all that stuff.

A lot of the time the experts, the people who are supposed to be able to tell you what to do, will tell you that you can't do something even when you know you can. And a lot of the time it's your friends ... who tell you you can do it.

[Facebook] is shaping a broader web. If you look back for the past five or seven years, the story about social networking has really been about getting people connected... But if you look forward for the next five years, I think that the story people are going to remember five years from now isn't how this one site was built; it is how every single service that you use is now going to be better with your friends.

The thing that we are trying to do at Facebook is just help people connect and communicate more efficiently.

By giving people the power to share, we're making the world more transparent.
