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.

Move fast, take risks, it's okay to try big things you're better off trying something and having it not work and learning from that than having not done anything at all.

And connected is helping people stay in touch and maintain empathy for each other, and bandwidth.

There are social restrictions where someone could be suppressing someone else's freedom to express themselves.

We used to write this down by saying, 'move fast and break things.' And the idea was, unless you are breaking some stuff you are not moving fast enough. I think there's probably something in that for other entrepreneurs to learn which is that making mistakes is okay. At the end of the day, the goal of building something is to build something, not to not make mistakes.

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.

This is a perverse thing, personally, but I would rather be in the cycle where people are underestimating us. It gives us latitude to go out and make big bets that excite and amaze people.
