Ensure that you do things differently from everyone else

I grew up in a house where my father encouraged my brother and me to fail. I specifically remember coming home and saying, 'Dad, Dad, I tried out for this or that and I was horrible,' and he would high-five me and say, 'Way to go.'

What you don’t know can be your greatest asset.

Within the first year of launching my company, Spanx, I decided to go over to England and cold-call Harrods, Harvey Nichols, and Selfridges the same way I had cold-called Neiman Marcus, Saks, Nordstrom, and Bloomingdale's here in the United States.

Failure is not attached to outcome, but in not trying. This way, it is about answering to yourself.

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.

What I most identify with is effortless fashion, looking as if someone's not put a lot of effort into their look.
