Only great people can make great products.

Facebook has woven itself into the fabric of our lives and the foundation of the Internet. I think everything will be redefined because people are using their real identities on the Internet.

When I started Cove, I spoke to three immigration lawyers who gave me a long checklist of things to do before my company could hire immigrants.

If I don't ask for something, I'm not going to get it.

When I started out in Facebook, it had only 20 people. I saw it grow to a thousand employees and from five million users to over a billion users. I saw it evolve from a service that served college students to one that served the world.

How would you have done things differently if you were not afraid?

Only great people can make great products.
