Tim Ferris came out with his famous (read: controversial) book, The four-Hour Workweek: Escape 9-5, Live Anywhere, and Join the New Rich in 2007. The book has sold more than 1.3 million copies and has been translated into 35 languages. Not only this, but the book has also been a New York Times bestseller for more than four years.
The core idea behind the book is to work less and make more money. Pretty much like the saying "work smarter, not harder."
