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

You’ve got to embrace what you don’t know.

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.

I'll mix a lot of things. I'll wear a Temperley dress with flip flops, or I might be in head-to-toe Gucci and have on a ring that I got from a gumball machine for 50 cents.

Ideas, even million-dollar ones, are most vulnerable in their infancy; don't share them with too many people. However, don't hide your plan from people who can help you move it forward.

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.

Failure is not the outcome - failure is not trying. Don't be afraid to fail.
