Sara Blakely is a self-made billionaire selling very effective women's underwear, Spanx. She is, at 41, the youngest woman who made her own fortune on the Forbes list of the world's richest people.
She invented her product and her business herself, while also being married and a mother. This fact would not be remarkable for a man, but is very unusual for a female CEO.
She cites as her influences, all from afar at first, Wayne Dyer, Richard Branson, and Oprah Winfrey. She learned from failure. She overcame her fears. She seems to be a decent person.
And now she promotes other female entrepreneurs, just to give back.
