TED Talk by Derek Sivers
If you have not read or listen to Derek Sivers, I strongly suggest that you do. Think of him as a philosopher-king programmer and a master teacher. Originally a professional musician and circus clown, Derek created CD Baby in 1998. It became the largest seller of independent music online, with $100 million in sales for 150,000 musicians. He also has a website where you can read his notes on some of his favorite books. https://sivers.org/book
