When you want to change things, you can't please everyone. If you do please everyone, you aren't making enough progress.

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.

The most important thing is to keep your team as small as possible.

We want Facebook to be one of the best places people can go to learn how to build stuff.

There is something wrong with our system when I can leave here and make billions of dollars in 10 years while millions of students can't even afford to pay off their loans, let alone start a business. We all know you don't get successful just by having a good idea or working hard. You get successful by being lucky too. If I had to support my family growing up, instead of having the time to learn how to code. If I didn't know that I was gonna be fine if Facebook didn't work out, then I wouldn't be standing up here today. And if we're honest, we all know how much luck we've had.

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.

The trick isn't adding stuff, it's taking away.
