Meet Frank Warren, the person who likely keeps the most secrets in the world. In fact, he has a whole room in his house devoted to storing them. You’re probably familiar with Frank: He’s the founder of PostSecret. Twelve years ago, he asked people to anonymously send their secrets to him on a prestamped postcard. Over a decade later, his social experiment turned into one of the most-visited ad-free blogs in the world. In this episode, Frank shares why vulnerability was the key to PostSecret’s growth, and how it can be used to strengthen your core relationships, leadership skills, and business.
