Whenever I go to a new city, in order to help get on the right time zone and actually get a chance to see that city, I like running.

We're really at this point where we can take a step back and think about the next big things that we want to do.

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

Berlin definitely has one of the most vibrant of the startup scenes that I have seen. Not really just across Europe, but across the whole world in terms of cities. It's an interesting dynamic.

All of my friends who have younger siblings who are going to college or high school - my number one piece of advice is: You should learn how to program.

It used to be the case, like, you'd switch jobs, and then maybe you wouldn't keep in touch with all the people that you knew from that old job. Just because it was too hard. But one of the things that Facebook does is it makes it really easy to just stay in touch with all these people.

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.
