What I tell everyone, and I really do for myself is, I have a long-run dream, which is I want to work on stuff that I think matters.

The cost of stability is often diminished opportunities for growth.

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.

If you ask men why they did a good job, they'll say, 'I'm awesome. Obviously. Why are you even asking?' If you ask women why they did a good job, what they'll say is someone helped them, they got lucky, they worked really hard.

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.
