The reason I wrote Lean In is I think people weren't actually noticing that we had stopped making progress. I gave a TED talk and said: "It turns out men still run the world." And the audience gasped as if that was news.

Leadership is not bullying and leadership is not aggression. Leadership is the expectation that you can use your voice for good. That you can make the world a better place.

Trying to do it all and expecting that it all can be done exactly right is a recipe for disappointment. Perfection is the enemy.

Don't let your fears overwhelm your desire. Let the barriers you face-and there will be barriers-be external, not internal. Fortune does favor the bold, and I promise that you will never know what you're capable of unless you try.

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.

Its time to cheer on girls and women who want to sit at the table

I don't hold myself out as a role model. I don't believe that everyone should make the same choices; that everyone has to want to be a CEO, or everyone should want to be a work-at-home mother. I want everyone to be able to choose. But I want us to be able to choose unencumbered by gender choosing for us.
