Facebook is a really exciting place trying to do something really important that I really believe in. And it matters.

The reason I wrote Lean In is I think people weren't actually noticing that we had stopped making progress. I gave a TED talk and said: "It turns out men still run the world." And the audience gasped as if that was news.

Success for me is that if my son chooses to be a stay-at-home parent, he is cheered on for that decision. And if my daughter chooses to work outside the home and is successful, she is cheered on and supported.

People think that women don't negotiate because they're not good negotiators, but that's not it. Women don't negotiate because it doesn't work as well for them. Women have to say, 'I really add a lot of value, and it's in your interest to pay me more.' I hate that advice, but I want to see women get ahead.

If more women are in leadership roles, we'll stop assuming they shouldn't be.

It's more pressure on women to - if they marry or partner with someone, to partner with the right person. Because you cannot have a full career and a full life at home with your children if you are also doing all of the housework and child care.

Being confident and believing in your own self-worth is necessary to achieving your potential.
