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.

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.

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.

There's no easy path through grief and trauma. Learning from the experiences of people who'd been through similar losses was helpful.

Women systematically underestimate their own abilities.

All of us want the same things. We want to be good to the people around us and for our lives to have meaning. For me that means making the world a little bit easier for women.

I gave a talk on gender stuff at Facebook one morning and a man didn't come. It was optional; he didn't have to come. But he sent a note saying, "I missed your meeting because I drove my kids to school so my wife could do something else. Thank you for making that possible." I think that employee is a loyal employee for Facebook and I think more companies should want that kind of loyalty.
