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.

In fact, my New Year's resolution every year, and I'm Jewish so I get two New Years a year, is to meditate, and I fail every time.

We know that the only way to achieve equality is if both men and women want to achieve equality. We also know that equality is not just the right thing to do for men, it is a good thing to do.

Two things that I think matter are gratitude and joy.

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.

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

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.
