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.

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.

When you're more valuable, the people around you will do more to make it work.

Its time to cheer on girls and women who want to sit at the table

A truly equal world would be one where women ran half our countries and companies and men ran half our homes.

I was grateful that Facebook already had generous bereavement policies . Now Facebook employees receive 20 days paid leave to grieve the loss of an immediate family member and 10 days for an extended family member. I'm proud that we're able to do this and I hope more businesses do the same. Only 60 percent of private sector workers get paid time off after the death of a loved one, and then it's usually just a few days. Workers and families deserve better than that.

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.
