Men feel like they can be a professional and a father. For women it's "or." That's offensive to me. The concept that it's not possible is crazy.

I am saying that I was able to mold those hours around the needs of my family, and that matters. And I really encourage other people at Facebook to mold hours around themselves.

Women attribute their success to working hard, luck, and help from other people. Men will attribute that - whatever success they have, that same success - to their own core skills.

In fact, my New Year's resolution every year, and I'm Jewish so I get two New Years a year, is to meditate, and I fail every time.

I'm not telling women to be like men. I'm telling us to evaluate what men and women do in the workforce and at home without the gender bias.

I don't pretend there aren't biological differences, but I don't believe the desire for leadership is hardwired biology, not the desire to win or excel. I believe that it's socialization, that we're socializing our daughters to nurture and our boys to lead.

I feel really grateful to the people who encouraged me and helped me develop. Nobody can succeed on their own.
