My dad encouraged us to fail. Growing up, he would ask us what we failed at that week. If we didn't have something, he would be disappointed. It changed my mindset at an early age that failure is not the outcome, failure is not trying. Don't be afraid to fail.

My training of cold-calling and everyone under the sun telling me no, and my keeping going, was a huge part of the first two years of Spanx.

I aim to be pretty - I gave up dressing to be sexy in the eighties.

I was trying to convince all these men to try to make a product that they didn't even wear! Or if they did wear them, they were not admitting it! There was the problem right there. No wonder their hosiery was so uncomfortable.

I'm 23 years old. I might just be my mother's child, but in all reality, I'm everybody's child. Nobody raised me; I was raised in this society.

My work often takes me away from my family for long periods of time, so I've really come to appreciate the time I do spend with them.

I had written two or three books before my husband noticed that in every one of them a family member was missing. He suggested that it was because my father's death, when I was five, utterly changed my world. I can only suppose he is right and that this is the reason I am drawn to a narrative where someone's life is changed by loss.

Getting married and starting a family has been a lifelong goal and one that I have persevered through different paths up to it!
