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

There is no perfect fit when you're looking for the next big thing to do. You have to take opportunities and make an opportunity fit for you, rather than the other way around. The ability to learn is the most important quality a leader can have.

I'm not pretending I can give advice to every single person or every single couple for every situation; I'm making the point that we are not going to get to equality in the workforce before we get to equality in the home. Not going to happen.

I'd worked on leprosy and malaria in India [at the World Bank] and asked myself the question: Why do we let 2 million children die every year around the world for not having clean water? Because they're faceless and nameless. So, for me, Facebook looked like it was going to solve the problem of the invisible victim.

Speak up. Believe in yourself. Take risks.

Women systematically underestimate their own abilities.

We have a problem with women in leadership across the board. This leadership gap - this problem of not enough women in leadership - is running really deep and it's in every industry. My answer is we have to understand the stereotype assumptions that hold women back.
