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.

There is no perfect fit when you're looking for the next big thing to do. You have to take opportunities and make an opportunity fit for you, rather than the other way around. The ability to learn is the most important quality a leader can have.

Our aspirations are really for women to be in half the leadership roles and men to be doing half the work of parenting.

When companies offer support and assistance for personal and family hardships, their employees become more loyal and more productive.

Facebook is a really exciting place trying to do something really important that I really believe in. And it matters.

But I really believe that when you give people authentic identity, which is what Facebook does, and you can be your real self and connect with real people online, things will change.
