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.

Women have made tons of progress. But we still have a small percentage of the top jobs in any industry, in any nation in the world. I think that's partly because from a very young age, we encourage our boys to lead and we call our girls bossy.

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

You know, there has never been a 24-hour period in five years when I have not responded to e-mail at Facebook. I am not saying it's easy. I work long hours.

I'm not telling women to be like men. I'm telling us to evaluate what men and women do in the workforce and at home without the gender bias.

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.

The traditional metaphor for careers is a ladder, but I no longer think that metaphor holds. It just doesn’t make sense in a less hierarchical world... Build your skills, not your resume. Evaluate what you can do, not the title they’re going to give you. Do real work. Take a sales quota, a line role, an ops job. Don’t plan too much, and don’t expect a direct climb. If I had mapped out my career when I was sitting where you are, I would have missed my career.
