The 4-Hour Workweek: Escape 9-5, Live Anywhere, and Join the New Rich is a 2007 New York Times Best Seller self-help book written by Timothy Ferriss that offers the formula of escaping the rat race, outsourcing a business, and living your life to the fullest. Ferriss developed the ideas in the book while working 14-hour days and 100-hour weeks at his sports nutrition supplement company. Frustrated by the overwork and lack of free time, he took a 3-week sabbatical leave to Europe and ended up extending that trip to a year throughout Asia and South America. Ferriss developed a streamlined system of operating his business without his presence, that was able to yield 10 times more income than when he was personally involved in it.
