I'm trying to make the world a more open place by helping people connect and share.

If there is a bug in your code than you have to drop everything you're doing and go fix it.

I think I've grown and learned a lot.

Providing the best photo sharing experience is one reason why so many people love Facebook and we knew it would be worth bringing these two companies together.

I don't hate anybody. The Winklevi aren't suing me for intellectual property theft. They're suing me because for the first time in their lives, the world didn't work the way it was supposed to for them.

I mean, we've built a lot of products that we think are good, and will help people share photos and share videos and write messages to each other. But it's really all about how people are spreading Facebook around the world in all these different countries. And that's what's so amazing about the scale that it's at today.

The question I ask myself like almost every day is: ‘Am I doing the most important thing I could be doing?' Unless I feel like I’m working on the most important problem that I can help with, then I’m not going to feel good about how I’m spending my time. And that’s what this company is.
