"I started the site when I was 19. I didn't know much about business back then."

"I think a simple rule of business is, if you do the things that are easier first, then you can actually make a lot of progress."

"I think humans are just hard-wired to process people's faces and understand meaning and expression at such a more granular level than other types of communication."

"My goal was never to make Facebook cool. I am not a cool person."

"Our goal is to make it so there's as little friction as possible to having a social experience."

"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."

"The real story of Facebook is just that we've worked so hard for all this time. I mean, the real story is actually probably pretty boring, right? I mean, we just sat at our computers for six years and coded."

"The thing that we are trying to do at facebook, is just help people connect and communicate more efficiently."

"There is a huge need and a huge opportunity to get everyone in the world connected, to give everyone a voice and to help transform society for the future. The scale of the technology and infrastructure that must be built is unprecedented, and we believe this is the most important problem we can focus on."

"Think about what people are doing on Facebook today. They're keeping up with their friends and family, but they're also building an image and identity for themselves, which in a sense is their brand. They're connecting with the audience that they want to connect to. It's almost a disadvantage if you're not on it now."
