Most of the reason we don’t do things is because we’re afraid to fail. I just made a decision one day that I was not not going to do things in my life because of fear.

The smartest thing I ever did was to hire my weakness.

When I was growing up, my dad would encourage my brother and I to fail. We would be sitting at the dinner table and he would ask, 'So what did you guys fail at this week?' If we didn't have something to contribute, he would be disappointed. When I did fail at something, he'd high-five me. What I didn't realize at the time was that he was completely reframing my definition of failure at a young age. To me, failure means not trying; failure isn't the outcome. If I have to look at myself in the mirror and say, 'I didn't try that because I was scared,' that is failure.

Everything about my journey to get Spanx off the ground entailed me having to be a salesperson - from going to the hosiery mills to get a prototype made to calling Saks Fifth Avenue and Neiman Marcus. I had to position myself to get five minutes in the door with buyers.

Don't let what you don't know scare you, because it can become your greatest asset. And if you do things without knowing how they have always been done, you're guaranteed to do them differently.

I pledge to invest in women because I believe it offers one of the greatest returns on investment. I am committed to the belief that we would all be in a much better place if half the human race (women) were empowered to prosper, invent, be educated, start their own businesses, run for office essentially be given the chance to soar.

Where I get my energy is: 'How can I make it better'?
