Everything in our society is so purposeful.

My advice for an entrepreneur just starting out is to differentiate yourself. Why are you different? What’s important about you? Why does the customer need you?

I'm obsessed with the customer. I am the customer. I really don't think you can go wrong if you don't take your eye off of that. Serving the customer. How does she feel? I feel like the fashion industry has cared a lot about how we look but not about how we feel.

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.

When I was a child, my father used to encourage my brother and me to fail. At the dinner table, instead of asking about the best part of our day, he would ask us what we failed at that week. If we didn't have something to tell him, he would be disappointed. When we shared whatever failure we'd endured, he'd high-five us and say, 'Way to go!' The gift my father gave us by doing this was redefining what failure truly meant.

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.

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.
