Tim Ferriss changed my life with his book, The 4-Hour Workweek: Escape 9-5, Live Anywhere, and Join the New Rich. In fact, I still remember being inn Las Vegas, with a girl, thinking, “Wow, my small business is still making just as much money as it would have if I was in town and I’m on vacation.” That book was absolutely brilliant, but just crediting him with that book sells him short.
