If I had to embrace a definition of success, it would be that success is making the best choices we can ... and accepting them.

When the man is traveling with a man, he says, "Let's stay up late and work on this and get this to be better." When the man's traveling with the woman, for the sake of appearances he doesn't do the work with her. That's a lost opportunity for her to be a success.

You know, there has never been a 24-hour period in five years when I have not responded to e-mail at Facebook. I am not saying it's easy. I work long hours.

I believe we need affordable child care. I believe we need flexibility. I believe we need institutional reform and public policy reform.

Pages on Facebook are allowed to be anonymous. That is really important. People start revolutions; we need anonymity.

Talking can transform minds, which can transform behaviors, which can transform institutions.

But I really believe that when you give people authentic identity, which is what Facebook does, and you can be your real self and connect with real people online, things will change.
