Building a mission and building a business go hand-in-hand. It is true that the primary thing that makes me excited about what we're doing is the mission, but I also think, from the very beginning, we've had this healthy understanding which is that we need to do both.

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.

The question isn't, 'What do we want to know about people?', It's, 'What do people want to tell about themselves?'

If things aren’t breaking, then you’re not moving fast enough. People learn by making mistakes.

In addition to building better products, a more open world will also encourage businesses to engage with their customers directly and authentically. More than four million businesses have Pages on Facebook that they use to have a dialogue with their customers. We expect this trend to grow as well.

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

Don't discount yourself, no matter what you're doing. Everyone has a unique perspective that they can bring to the world.
