Tim Ferriss is an extraordinary young man on a mission. The twenty-eight-year-old serial vagabond and successful entrepreneur has been teaching a wildly popular course at Princeton University for the past four years--a how-to and why-to guide to throwing out the old tools and methods for success (balancing life and work, retiring well, having a great nest egg) and replacing them with a whole new way of living. Readers can lead a rich life by working only four hours a week, freeing up the rest of their time to spend it living the lives they want.
