The thing I really care about is the mission, making the world open.

Facebook was not originally created to be a company. It was built to accomplish a social mission - to make the world more open and connected.

When I started Facebook from my dorm room in 2004, the idea that my roommates and I talked about all the time was a world that was more open.

I'm trying to make the world a more open place.

It's really easy to have a nice philosophy about openness, but moving the world in that direction is a different thing. It requires both understanding where you want to go and being pragmatic about getting there.

Our philosophy is that we care about people first.
