I just believed. I believed that the technology would change people's lives. I believed putting real identity online - putting technology behind real identity - was the missing link.

What works for men does not always work for women, because success and likability are positively correlated for men and negatively correlated for women. That's what the research shows. As a man gets more successful, everyone is rooting for him. As a woman gets more successful, both men and women like her less.

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

We need women at all levels, including the top, to change the dynamic, reshape the conversation, to make sure women’s voices are heard and heeded, not overlooked and ignored.

At Facebook, we try to be a strengths-based organization, which means we try to make jobs fit around people rather than make people fit around jobs. We focus on what people's natural strengths are and spend our management time trying to find ways for them to use those strengths every day.

It is illegal to discriminate on the basis of pregnancy or gender. It is not illegal to talk about it.

Real change will come when powerful women are less of an exception. It is easy to dislike senior women because there are so few.
