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.

If Facebook were a country, it would be the 8th most populated in the world, just ahead of Japan.

When you give people ability to stay connected with all the people they care about, and you make it so they can express new things about themselves or in communication with other people who they care about, then you just open up new possibilities. You make it so people can stay connected in ways that they couldn't before.

I literally coded Facebook in my dorm room and launched it from my dorm room. I rented a server for $85 a month, and I funded it by putting an ad on the side, and we've funded ever since by putting ads on the side.

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

There are a few other things that I built when I was at Harvard that were kind of smaller versions of Facebook.

The ability to share whole scenes form our lives will be a valuable thing over time.
