I just believed. I believed that the technology would change people's lives. I believed putting real identity online - putting technology behind real identity - was the missing link.

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.

My hope in writing 'Lean In: Women, Work, and the Will to Lead' was to change the conversation from what women can't do to what we can.

I wish I could just go tell all the young women I work with, all these fabulous women, 'Believe in yourself and negotiate for yourself. Own your own success.' I wish I could tell that to my daughter. But it's not that simple.

I tell people in their careers, 'Look for growth. Look for the teams that are growing quickly. Look for the companies that are doing well. Look for a place where you feel that you can have a lot of impact.'

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

The most important thing we're doing differently is that we talk openly about gender at Facebook.
