Advertising works most effectively when it's in line with what people are already trying to do.

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.

We also have a dog. His name's Beast. He's a sheepdog. He's super cute. I love him.

We used to write this down by saying, 'move fast and break things.' And the idea was, unless you are breaking some stuff you are not moving fast enough. I think there's probably something in that for other entrepreneurs to learn which is that making mistakes is okay. At the end of the day, the goal of building something is to build something, not to not make mistakes.

Advertising works most effectively when it's in line with what people are already trying to do. And people are trying to communicate in a certain way on Facebook - they share information with their friends, they learn about what their friends are doing - so there's really a whole new opportunity for a new type of advertising model within that.

I just think people have a lot of fiction. But, you know, I mean, the real story of Facebook is just that we've worked so hard for all this time. I mean, the real story is actually probably pretty boring, right? I mean, we just sat at our computers for six years and coded.
