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.

Feeling confident - or pretending that you feel confident - is necessary to reach for opportunities. It's a cliché, but opportunities are rarely offered; they're seized.

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.

There are really good reasons to leave the workforce or work less or take a different job when you want to be with your children. I just want women - and men - to make that choice once they have the child. Not years in advance, because... they don't get the right opportunities. They give up before they even start.

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.

I have a five year-old son and a three year-old daughter. I want my son to have a choice to contribute fully in the workforce or at home. And I want my daughter to have the choice to not just succeed, but to be liked for her accomplishments.

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.
