There is no straight path from your seat today to where you are going. Don't try to draw that line. You will not just get it wrong, you'll miss big opportunities. And I mean big-like the Internet. Careers are not ladders, those days are long gone, but jungle gyms. Don't just move up and down, don't just look up, look backwards, sideways around corners. Your career and your life will have starts and stops and zigs and zags. Don't stress out about the white space-the path you can't draw- because there in lies both the surprises and the opportunities.

I'd worked on leprosy and malaria in India [at the World Bank] and asked myself the question: Why do we let 2 million children die every year around the world for not having clean water? Because they're faceless and nameless. So, for me, Facebook looked like it was going to solve the problem of the invisible victim.

We call our little girls bossy. Go to a playground; little girls get called bossy all the time - a word that's almost never used for boys - and that leads directly to the problems women face in the workforce.

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

The social web can't exist until you are your real self online. I have to be me. You have to be you. Once we are online as ourselves, connected to each other and our other friends, then you can have the evolution of what becomes the social web.

Pages on Facebook are allowed to be anonymous. That is really important. People start revolutions; we need anonymity.

When I was in high school, I was voted most likely to succeed.
