When my mother took her turn to sit in a gown at her graduation, she thought she only had two career options: nursing and teaching. She raised me and my sister to believe that we could do anything, and we believed her.

My goal is very clear, and I wrote about it in Lean In, which is that women run half our companies and countries and men run half our homes. As much as I wish that could happen in four years, I don't think that's a likely time period. But I think it can happen sooner than we think. Part of it is having that aspiration and that goal. I think we too often suffer from the tyranny of low expectations.

A lot of people will say, "what's Facebook's business model?" I always find that a kind of funny question. Our business model is out there, which is: we monetize largely through advertising and a little bit through the gift revenue, the virtual gifts we have on our site. I think those continue to be the most promising avenues going forward.

Grief affects job performance, so giving workers time off to grieve can lead to stronger outcomes at work.

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

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