I think I've grown and learned a lot.

In a recent survive of Millennials around the world asking what most defines our identity, the most popular wasn't nationality, ethnicity or religion. It was "citizen of the world." That's a big deal. Every generation expands the circle of people we consider one of us. And in our generation, that now includes the whole world. This is the struggle of our time. The forces of freedom, openness, and global community against the forces of authoritarianism, isolationism, and nationalism - forces for the flow of knowledge, trade, and immigration, against those who would slow them down.

[Facebook] is shaping a broader web. If you look back for the past five or seven years, the story about social networking has really been about getting people connected... But if you look forward for the next five years, I think that the story people are going to remember five years from now isn't how this one site was built; it is how every single service that you use is now going to be better with your friends.

Critics worry that if we spend time paying attention to that new kind of media or technology instead of talking to each other that that is somehow isolating. But humans are fundamentally social. So I think in reality, if a technology doesn't actually help us socially understand each other better, it isn't going to catch on and succeed.

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.

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.

People at Facebook are fairly used to the press being nice to us or not nice to us.
