We talk about this concept of openness and transparency as the high-level ideal that we're moving towards at Facebook. The way that we get there is by empowering people to share and connect. The combination of those two things leads the world to become more open.

I feel that the best companies are started not because the founder wanted a company but because the founder wanted to change the world... If you decide you want to found a company, you maybe start to develop your first idea. And hire lots of workers.

I always tell people that you should only hire people to be on your team if you would work for them.
