I'm trying to make the world a more open place by helping people connect and share.

I think that more flow of information, the ability to stay connected to more people makes people more effective as people. And I mean, that's true socially. It makes you have more fun, right. It feels better to be more connected to all these people. You have a richer life.

It took 10 years to go from building the initial Smartphone to reaching the mass market. BlackBerry came out in 2003 and it didn't get to about a billion units until 2013. So I can't imagine it would be much faster for VR.

I'd like to show an improved product rather than just talk about things we might do.

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.

Facebook is uniquely positioned to answer questions that people have, like, what sushi restaurants have my friends gone to in New York lately and liked? These are queries you could potentially do with Facebook that you couldn't do with anything else, we just have to do it.

My friends are people who like building cool stuff. We always have this joke about people who want to just start companies without making something valuable. There's a lot of that in Silicon Valley.
