In terms of doing work and in terms of learning and evolving as a person, you just grow more when you get more people's perspectives... I really try and live the mission of the company and... keep everything else in my life extremely simple.

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

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

Advertising works most effectively when it's in line with what people are already trying to do. And people are trying to communicate in a certain way on Facebook - they share information with their friends, they learn about what their friends are doing - so there's really a whole new opportunity for a new type of advertising model within that.

Helping a billion people connect is amazing, humbling and by far the thing I am most proud of in my life.

When you give everyone a voice and give people power, the system usually ends up in a really good place. So, what we view our role as, is giving people that power.

There have been misperceptions that we're trying to make all the information open on Facebook, and that's completely false. There are big buckets of information that we recommend that you share with only your friends privately. Then some of the more basic information, we recommend that that's visible to everyone.
