It's pretty exciting to take real people living in the real world, their opinions, and have people have to react to that. As opposed to their perceptions of what people are thinking, which are often very different.

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.

Aggressive and hard-charging women violate unwritten rules about acceptable social conduct. Men are continually applauded for being ambitious and powerful and successful, but women who display these same traits often pay a social penalty. Female accomplishments come at a cost.

We have to ask ourselves if we have become so focused on supporting personal choices that we're failing to encourage women to aspire to leadership.

No industry or country can reach its full potential until women reach their full potential. This is especially true of science and technology, where women with a surplus of talent still face a deficit of opportunity.

The most important thing we're doing differently is that we talk openly about gender at Facebook.

Someone who values fairness and expects or, even better, wants to do his share in the home. These men exist and, trust me, over time, nothing is sexier.
