When I was a smelly 23-year-old, I was unemployed and living on a friend’s couch. I would pass my days at the bookstore picking up books that looked interesting, reading a chapter or two, putting it back, and going home. I turned that store into my own personal library. Thank god the clerks never found out.

One day, I picked up a small book that mentioned a simple idea. Fifteen years later, the result of that idea would be 12 million books sold, speaking tours across five continents, and the website you are reading today.
