I think people tend to be worried about every new technology that comes along.

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.

In the olden times, privacy was good. Today people want to share, people are more open.

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's a difference between being obsessed and being motivated.

When I was in college, I remember thinking to myself, this internet thing is awesome because you can look up anything you want, you can read news, you can download music, you can watch movies, you can find information on Google, you can get reference material on Wikipedia, except the thing that is most important to humans, which is other people, was not there.

Find that thing you are super passionate about. A lot of founding principles of Facebook are that if people have access to more information and are more connected, it will make the world better; people will have more understanding, more empathy. That’s the guiding principle for me. On hard days, I really just step back, and that’s the thing that keeps me going.
