When I went to college, as much as my parents emphasized academic achievement, they emphasized marriage even more. They told me that the most eligible women marry young to get a 'good man' before they are all taken.

Excel and you will get a mentor.

When we get feedback on women, we ask, "Is that real or is that the gender bias at play?" Everyone could start doing that today and I think we'd see really big results.

People assume Wall Street is a certain culture and tech is a certain culture. But if you look at the (gender) numbers at the top of (those) industries, they don't vary very much. I think in finance, women hold 19 percent of the top jobs, and women are 21 percent of the leaders in nonprofits.

Over the last 10 years, women have stalled out at the top.

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.

And in situations where a man and a woman each receive negative feedback, the woman's self-confidence and self-esteem drop to a much greater degree. The internalization of failure and the insecurity it breeds hurt future performance, so this pattern has serious long-term consequences.
