At Facebook, we try to be a strengths-based organization, which means we try to make jobs fit around people rather than make people fit around jobs. We focus on what people's natural strengths are and spend our management time trying to find ways for them to use those strengths every day.

The best decision I ever made was to marry Dave.

Let's acknowledge that men reach for opportunities more quickly and more easily than women. So often as managers, we give the job to whoever starts solving the problem, to whoever jumps in. Since we know men will jump in faster than women in so many circumstances, we have to slow down and encourage more women to sit at more tables.

I really think we need more women to lean into their careers and to be really dedicated to staying in the work force.

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?

I gave a talk on gender stuff at Facebook one morning and a man didn't come. It was optional; he didn't have to come. But he sent a note saying, "I missed your meeting because I drove my kids to school so my wife could do something else. Thank you for making that possible." I think that employee is a loyal employee for Facebook and I think more companies should want that kind of loyalty.
