I started the site when I was 19. I didn't know much about business back then.

The real question for me is, do people have the tools that they need in order to make those decisions well? And I think that it's actually really important that Facebook continually makes it easier and easier to make those decisions... If people feel like they don't have control over how they're sharing things, then we're failing them.

I would only hire someone to work directly for me if I was willing to work for that person.

I actually remember very specifically the night that I launched Facebook at Harvard. I used to go out to get pizza with a friend who I did all my computer science homework with. And I remember talking to him and saying I am so happy we have this at Harvard because now our community can be connected but one day someone is going to build this for the world.

Move fast and break things. Unless you are breaking stuff, you are not moving fast enough.

So many businesses get worried about looking like they might make a mistake, they become afraid to take any risk.

Connectivity just can't be a privilege for people in the richest countries. We believe that connecting everyone in the world is one of the great challenges of our generation, and that's why we are happy to play whatever small part in that that we can.
