Grief comes and goes, it ebbs and flows. I think one of the lessons of this for me is that there's no one way to grieve. Everyone does it in their own way, in their own time, and we all process life and its challenges and its ups and downs as they come.

If you ask men why they did a good job, they'll say, 'I'm awesome. Obviously. Why are you even asking?' If you ask women why they did a good job, what they'll say is someone helped them, they got lucky, they worked really hard.

I have a five year-old son and a three year-old daughter. I want my son to have a choice to contribute fully in the workforce or at home. And I want my daughter to have the choice to not just succeed, but to be liked for her accomplishments.

I want women to get paid more. I want to teach them to negotiate so they get paid more.

There are really good reasons to leave the workforce or work less or take a different job when you want to be with your children. I just want women - and men - to make that choice once they have the child. Not years in advance, because... they don't get the right opportunities. They give up before they even start.

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.

In fact, my New Year's resolution every year, and I'm Jewish so I get two New Years a year, is to meditate, and I fail every time.
