Tim Ferriss, the controversial figure behind the bestselling 4 Hour Work Week and other motivational books, is coming out with a new book, Tools of Titans: The Tactics, Routines, and Habits of Billionaires, Icons, and World-Class Performers. If you're looking for a book to help you get more motivated in 2017, consider taking a leaf out of Ferriss - but be warned, it's highly unlikely the "billionaires, icons, and world-class performers" only work 4 hours a week.
