Facebook is great for women and men. We are enormously flexible. We care a lot about great opportunities for women, we push ourselves to make things as flexible as possible.

When looking for a life partner, my advice to women is date all of them: the bad boys, the cool boys, the commitment-phobic boys, the crazy boys. But do not marry them. The things that make the bad boys sexy do not make them good husbands. When it comes time to settle down, find someone who wants an equal partner. Someone who thinks women should be smart, opinionated and ambitious. Someone who values fairness and expects or, even better, wants to do his share in the home. These men exist and, trust me, over time, nothing is sexier.

We know when we use the full talents of our population we're more productive. And we know that when people really feel like they can have flexible lives, they're better employees.

The most important career decision you'll make is who your life partner is.

I think when tragedy occurs, it presents a choice. You can give in to the void, the emptiness that fills your heart, your lungs, constricts your ability to think or even breathe. Or you can try to find meaning. These past thirty days, I have spent many of my moments lost in that void. And I know that many future moments will be consumed by the vast emptiness as well. But when I can, I want to choose life and meaning.

I spent most of my career, including my time at McKinsey, never acknowledging that I was a woman. And, you know, fast forward - I'm 43 now - fitting in is not helping us.

I tell people in their careers, 'Look for growth. Look for the teams that are growing quickly. Look for the companies that are doing well. Look for a place where you feel that you can have a lot of impact.'
