I have never worked for a woman, and I have never worked with a lot of women.

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.

Until women are as ambitious as men, they're not gong to achieve as much as men.

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.

...parents who work outside the home are still capable of giving their children a loving and secure childhood. Some data even suggest that having two parents working outside the home can be advantageous to a child's development, particularly for girls.

Women systematically underestimate their own abilities.

I'm not pretending I can give advice to every single person or every single couple for every situation; I'm making the point that we are not going to get to equality in the workforce before we get to equality in the home. Not going to happen.
