Sara Blakely, Founder of Spanx
She is the youngest female self-made billionaire in the U.S. She is also the first female billionaire to join the Giving Pledge, started by Warren Buffett and Bill Gates, in which the wealthiest individuals worldwide pledge to donate at least half to their wealth to charity.
“Believe in your idea, trust your instincts, and don’t be afraid to fail. It took me two years from the time I had the idea for Spanx until the time I had a product in hand ready to sell into stores. I must have heard the word “no” a thousand times. If you believe in your idea 100%, don’t let anyone stop you! Not being afraid to fail is a key part of the success of Spanx.”
