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

Our strategy is very horizontal. We're trying to build a social layer for everything. Basically we're trying to make it so that every app everywhere can be social whether it's on the web, or mobile, or other devices.

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

When people are connected, we can just do some great things. They have the opportunity to get access to jobs, education, health, communications. We have the opportunity to bring the people we care about closer to us.

Connecting the world is really important, and that is something that we want to do. That is why Facebook is here on this planet.

There are many machines throughout history that were built to do something better than a human can.

If you actually do something you love it's a lot easier and takes on a lot more purpose.
