At Facebook we feel a lot of affinity not just for this community but for any community that is trying to do what Davos is trying to do, which is to share information. And Davos is doing it in a particular way - I think the Facebook approach is obviously more broad-based, we're trying to include everyone in the world. But the goal is the same: bring people together, to share information and make the world more connected, and have people have a deeper understanding of themselves, others, the communities of which they want to be a part and can be a part.

We're focused on doing one thing incredibly well. If you look at other companies, all of these companies are doing a lot of different things but we're still, as we grow, doing exactly one thing.

I would be better at my job if I were technical.

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.

We've ceased making progress at the top in any industry anywhere in the world . In the United States, women have had 14% of the top corporate jobs and 17% of the board seats for 10 years. Ten years of no progress.

It is the ultimate luxury to combine passion and contribution. It's also a very clear path to happiness.

We can each define ambition and progress for ourselves. The goal is to work toward a world where expectations are not set by the stereotypes that hold us back, but by our personal passion, talents and interests.
