I'm excited that more people, especially men, are understanding that equality is good for them. I don't want men to want equality for women because they're being nice to their colleagues and daughters. I want men to want it because it's better for their companies and their lives.

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.

We need to talk more openly about mentorships and sponsorships. Women don't get the mentoring, and particularly the sponsors, they need to succeed as much as men.

When it comes time to settle down, find someone who wants an equal partner. Someone who thinks women should be smart, opinionated, and ambitious.

Go to a playground: Little girls get called 'bossy' all the time, a word that's almost never used for boys. And that leads directly to the problems women face in the workforce. When a man does a good job, everyone says, 'That's great.' When a woman does that same thing, she'll get feedback that says things like, 'Your results are good, but your peers just don't like you as much' or 'maybe you were a little aggressive.'

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.

I'd worked on leprosy and malaria in India [at the World Bank] and asked myself the question: Why do we let 2 million children die every year around the world for not having clean water? Because they're faceless and nameless. So, for me, Facebook looked like it was going to solve the problem of the invisible victim.
