No one gets to the top, if they sit on the sidelines, or if they don't believe in themselves.

Every job will demand some sacrifice. The key is to avoid unnecessary sacrifice.

Women systematically underestimate their own abilities.

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.

Give us a world where half our homes are run by men and half our institutions are run by women. I'm pretty sure that would be a better world.

We cannot change what we are not aware of, and once we are aware, we cannot help but change.

I realized that searching for a mentor has become the professional equivalent of waiting for Prince Charming. We all grew up on the fairy tale "Seeping Beauty," which instructs young women that if they just wait for their prince to arrive, they will be kissed and whisked away on a white horse to live happily ever after. Now young women are told that if they can just find the right mentor, they will be pushed up the ladder and whisked away to the corner office to live happily ever after. Once again, we are teaching women to be too dependent on others.
