Derek Sivers is one of the most fascinating guests we have ever interviewed. Part philosopher, part programmer, a master teacher, a best selling author Derek was originally a professional musician and circus clown. He created CD Baby the largest seller of independent music online, with $100 million in sales for 150,000 musicians. In 2008 he sold CD Baby for $22 million, giving the entire proceeds to a charitable trust for music education. He's published 34 books, including Anything you Want.
