Your life's course will not be determined by doing the things that you are certain you can do. Those are the easy things. It will be determined by whether you try the things that are hard.

We're focused on doing one thing incredibly well. If you look at other companies, all of these companies are doing a lot of different things but we're still, as we grow, doing exactly one thing.

When I went to college, as much as my parents emphasized academic achievement, they emphasized marriage even more. They told me that the most eligible women marry young to get a 'good man' before they are all taken.

I realized that searching for a mentor has become the professional equivalent of waiting for Prince Charming. We all grew up on the fairy tale "Seeping Beauty," which instructs young women that if they just wait for their prince to arrive, they will be kissed and whisked away on a white horse to live happily ever after. Now young women are told that if they can just find the right mentor, they will be pushed up the ladder and whisked away to the corner office to live happily ever after. Once again, we are teaching women to be too dependent on others.

The most important thing - and I've said it a hundred times and I'll say it a hundred times - if you marry a man, marry the right one.

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.

We've ceased making progress at the top in any industry anywhere in the world . In the United States, women have had 14% of the top corporate jobs and 17% of the board seats for 10 years. Ten years of no progress.
