The 4-hour Work Week

The 4-Hour Workweek: Escape 9–5, Live Anywhere, and Join the New Rich (2007) is a self-help book by Timothy Ferriss, an American writer, educational activist, and entrepreneur. It deals with what Ferriss refers to as "lifestyle design", and repudiates the traditional "deferred" life plan in which people work grueling hours and take few vacations for decades and save money in order to relax after retirement. The book spent four years on The New York Times Best Seller List, was translated into 40 languages, and sold around 2.1 million copies.
