"The biggest risk is not taking any risk... In a world that is changing really quickly, the only strategy that is guaranteed to fail is not taking risks"
"My friends are people who like building cool stuff. We always have this joke about people who want to just start companies without making something valuable. There's a lot of that in Silicon Valley"
"Facebook is in a very different place than Apple, Google, Amazon, Samsung, and Microsoft. We are trying to build a community"
"Our mission is to connect every person in the world. You don't do that by having a service people pay for"
"I feel like the thing we can do is celebrate people doing great work and create more cultural momentum and awareness that this is an important thing in the world. So when the next economic crisis hits and people are talking about where to cut from the budget, science isn't the thing"
"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"
"This is our commitment to users and the people who use our service, is that Facebook's a free service. It's free now. It will always be free. We make money through having advertisements and things like that"

"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"
"When Facebook was getting started, nothing used real identity - everything was anonymous or pseudonymous - and I thought that real identity should play a bigger part than it did"
"If you grew up, and you never had a computer, and you've never used the Internet, and someone asked you if you wanted to buy a data plan, your response would be 'What's a data plan, and why would I want to use this?'"
"We don't sell data; we don't allow anyone to sell data"
"I do everything on my phone as a lot of people do"
"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"
"If you're always under the pressure of real identity, I think that is somewhat of a burden"
"Bill Gates has always been a mentor and inspiration for me even before I knew him. Just growing up, I admired how Microsoft was mission-focused"
