I don't pretend there aren't biological differences, but I don't believe the desire for leadership is hardwired biology, not the desire to win or excel. I believe that it's socialization, that we're socializing our daughters to nurture and our boys to lead.

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.

We [Facebook] really believe in enabling people to be their authentic selves on the web, and enabling people to communicate directly with each other in a very personal way.

When people are really suffering, and we know they're suffering, that question can be a very difficult one. Inadvertently, I think without anyone meaning it, it communicates a lack of empathy.

When looking for a life partner, my advice to women is date all of them: the bad boys, the cool boys, the commitment-phobic boys, the crazy boys. But do not marry them. The things that make the bad boys sexy do not make them good husbands. When it comes time to settle down, find someone who wants an equal partner. Someone who thinks women should be smart, opinionated and ambitious. Someone who values fairness and expects or, even better, wants to do his share in the home. These men exist and, trust me, over time, nothing is sexier.

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.

Getting from point A to point Z can be daunting unless you remember that you don’t have to get from A to Z. You just have to get from A to B. Breaking big dreams into small steps is the way to move forward.
