In 1998, Sara Blakely set out with a big idea to revolutionize the undergarment industry. Overnight, she went from being a frustrated consumer to the brilliant inventor of SPANX. Sara acted as the product's number one salesperson, using her skills honed in fax machine sales to get SPANX everywhere from the shelves of Neiman Marcus to Oprah's Favorite Things. Sara was named one of the 100 Most Influential People in the world by TIME and was featured on the cover of Forbes Magazine as the youngest self-made female billionaire. Twenty-two years after starting the company, Sara sold a majority stake to Blackstone and became Executive Chairwoman. Sara shares how SPANX has been profitable since day one, why what you don't know can actually be your greatest asset, and why it's important to bucket your days to spend time on what you're best at.
