I have this system where if I buy three or four new things, I give away three or four things. Sometimes, it's a very painful system, but shopping is even better when you know that someone else who needs it will be getting. Keep the clothing karma going, I say.

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

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.

Everything in our society is so purposeful.

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.

If somebody can do something 80 percent as good as you think you would have done it yourself, then you've got to let it go.

I feel that women have been neglected, unnecessarily neglected and mistreated personally by the fashion industry and shapewear in that entire category was a definite place that we were neglected.
