We want Facebook to be one of the best places people can go to learn how to build stuff.

If things aren’t breaking, then you’re not moving fast enough. People learn by making mistakes.

You hear these stories about people who take apart their radio and put it back. Or just learn a lot from taking it apart. But I wasn't as into that stuff as I was just into how computer programs work.

The last six years have been a lot of coding and focus and hard work. But maybe it would be fun to remember it as partying and all this crazy drama.

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

We have a pretty ambitious goal for the world. What we think will make the Web better. What we think will make all these businesses that integrate with us run more effectively. I think if we stay focused on doing that, that's really the main thing that we need to do.

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.
