I'm excited that more people, especially men, are understanding that equality is good for them. I don't want men to want equality for women because they're being nice to their colleagues and daughters. I want men to want it because it's better for their companies and their lives.

When you want to change things, you won't please everyone.

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.

Done is better than perfect.

Fear is at the root of so many of the barriers that women face. Fear of not being liked. Fear of making the wrong choice. Fear of drawing negative attention. Fear of overreaching. Fear of being judged. Fear of failure. And the holy trinity of fear: the fear of being a bad mother/wife/daughter.

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 am saying that I was able to mold those hours around the needs of my family, and that matters. And I really encourage other people at Facebook to mold hours around themselves.
