My number one piece of advice is: you should learn how to program.

Building a mission and building a business go hand-in-hand. It is true that the primary thing that makes me excited about what we're doing is the mission, but I also think, from the very beginning, we've had this healthy understanding which is that we need to do both.

The unsupervised learning is the way most people will learn in the future. You have this model of how the world works in your head and you're refining it to predict what you think is going to happen in the future.

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.

We also have a dog. His name's Beast. He's a sheepdog. He's super cute. I love him.

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

People don't care about what someone says about you in a movie--or even what you say, right? They care about what you build.
