The last six years have been a lot of coding and focus and hard work. But maybe it would be fun to remember it as partying and all this crazy drama.

At Facebook, we're inspired by technologies that have revolutionized how people spread and consume information. We often talk about inventions like the printing press and the television - by simply making communication more efficient, they led to a complete transformation of many important parts of society. They gave more people a voice. They encouraged progress. They changed the way society was organized. They brought us closer together.

People will always want more immersive ways to express themselves. So if you go back ten years ago on the internet, most of what people shared and consumed was text. Now a lot of it is photos. I think, going forward, a lot of it is going to be videos, getting richer and richer.

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

Having two identities for yourself is an example of a lack of integrity.

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 look at Google and think they have a strong academic culture. Elegant solutions to complex problems.
