Don't solicit feedback on your product, idea or your business just for validation purposes. You want to tell the people who can help move your idea forward, but if you're just looking to your friend, co-worker, husband or wife for validation, be careful. It can stop a lot of multimillion-dollar ideas in their tracks in the beginning.

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.

Every time I went on stage I was so terrified I almost threw up.

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

The word 'Spanx' was funny. It made people laugh. No one ever forgot it.

I feel like money makes you more of who you already are.

I always joke and say I want to invent a comfortable stiletto and then retire.
