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.

A squirrel dying in front of your house may be more relevant to your interests right now than people dying in Africa.

I think as a company, if you can get two things right--having a clear direction on what you are trying to do and bringing in great people who can execute on the stuff--then you can do pretty well.

In a lot of ways Berlin is a symbol for me of Facebook's mission: bringing people together, connecting people and breaking down boundaries.

We've changed our internal motto from "Move fast and break things" to "Move fast with stable infrastructure."

We want Facebook to be one of the best places people can go to learn how to build stuff. If you want to build a company, nothing better than jumping in and trying to build one. But Facebook is also great for entrepreneurs/hackers. If people want to come for a few years and move on and build something great, that's something we're proud of.

The days of you having a different image for your work friends or co-workers and for the other people you know are probably coming to an end pretty quickly. Having two identities for yourself is an example of a lack of integrity.
