So please ask yourself: What would I do if I weren't afraid? And then go do it.

Our aspirations are really for women to be in half the leadership roles and men to be doing half the work of parenting.

I really think we need more women to lean into their careers and to be really dedicated to staying in the work force.

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.

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.

We need to start talking about child-rearing in the workplace.

Our culture needs to find a robust image of female success that is first, not male, and second, not a white woman on the phone, holding a crying baby.
