Until women are as ambitious as men, they're not gong to achieve as much as men.

Men can comfortably claim credit for what they do as long as they don't veer into arrogance. For women, taking credit comes at a real social and professional cost.

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

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.

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.

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.

Next time you're about to call your daughter bossy, take a deep breath and say, 'My daughter has executive leadership skills.'
