When the man is traveling with a man, he says, "Let's stay up late and work on this and get this to be better." When the man's traveling with the woman, for the sake of appearances he doesn't do the work with her. That's a lost opportunity for her to be a success.

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.

Women need to shift form thinking "I'm not ready to do that" to thinking "I want to do that- and I'll learn by doing it.

There's no easy path through grief and trauma. Learning from the experiences of people who'd been through similar losses was helpful.

We have to ask ourselves if we have become so focused on supporting personal choices that we're failing to encourage women to aspire to leadership.

Today, despite all of the gains we have made, neither men nor women have real choice. Until women have supportive employers and colleagues as well as partners who share family responsibilities, they don't have real choice. And until men are fully respected for contributing inside the home, they don't have real choice either.

Framing the issue of work-life balance - as if the two were dramatically opposed - practically ensures work will lose out. Who would ever choose work over life?
