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

Working with a lot of people at the same time is a task. I really like making stuff and getting stuff done. One of the things I really liked about Facebook was that I could always move so quickly. I wrote the original application in, like, nine days at the end of January.

A frustration I have is that a lot of people increasingly seem to equate an advertising business model with somehow being out of alignment with your customers. I think it's the most ridiculous concept.

We have these services that people love and that are drivers of data usage... and we want to work this out, so that way, it's a profitable model for our partners.

What really motivates people at Facebook is building stuff that they're proud of.

Mobile is a lot closer to TV than it is to desktop.

We want Facebook to be one of the best places people can go to learn how to build stuff. If you want to build a company, nothing better than jumping in and trying to build one. But Facebook is also great for entrepreneurs/hackers. If people want to come for a few years and move on and build something great, that's something we're proud of.

The connectivity declaration is about uniting the whole industry - a lot of companies that typically compete very fiercely - to push in a coherent direction.

While some doubted that connecting the world was actually important, we were building. While others doubted that this would be sustainable, you were forming lasting connections. We just cared more about connecting the world than anyone else. And we still do today.

We're running the company to serve more people.

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.

We help Chinese companies grow their customers abroad. They use Facebook ads to find more customers. For example, Lenovo used Facebook ads to sell its new phone. In China, I also see economic growth. We admire it.

At Facebook, we build tools to help people connect with the people they want and share what they want, and by doing this we are extending people's capacity to build and maintain relationships.

If we're trying to build a world-class News Feed and a world-class messaging product and a world-class search product and a world-class ad system, and invent virtual reality and build drones, I can't write every line of code. I can't write any lines of code.

Connectivity is a human right.

If you're always under the pressure of real identity, I think that is somewhat of a burden.

When people are connected, we can just do some great things. They have the opportunity to get access to jobs, education, health, communications. We have the opportunity to bring the people we care about closer to us. It really makes a big difference.

Founding a company is hard. Most of it isn't smooth. You'll have to make very hard decisions. You have to fire a few people. Therefore, if you don't believe in your mission, giving up is easy. The majority of founders give up. But the best founders don't give up.

What we figured out was that in order to get everyone in the world to have basic access to the Internet, that's a problem that's probably billions of dollars. Or maybe low tens of billions. With the right innovation, that's actually within the range of affordability.

Hackathons are these things where just all of the Facebook engineers get together and stay up all night building things. And, I mean, usually at these hackathons, I code too, just alongside everyone.

I think what we've found is that when you can use products with your friends and your family and the people you care about, they tend to be more engaging. I think that we're really going to see this huge shift where a lot of industry is and products are just going to be remade to be social.

I got my first computer in the 6th grade or so. As soon as I got it, I was interested in finding out how it worked and how the programs worked and then figuring out how to write programs at just deeper and deeper levels within the system.

I think Facebook is an online directory for colleges... If I want to get information about you, I just go to TheFacebook, type in your name, and it hopefully pulls up all the information I'd care to know about you.

Once you have a product that you are happy with, you the need to centralize things to continue growth.

If you look at the history of our country over the last 100 years, there have been periods where science and research have been celebrated. They were really kind of held up as heroes in society, which encouraged a generation of people to go into these fields.
