Today's guest is none other than Tim Ferriss, author of three #1 New York Times and Wall Street Journal bestsellers: The 4-Hour Workweek, The 4-Hour Body, and The 4-Hour Chef. In his own words "For the last two years, I've interviewed nearly two hundred world-class performers for my podcast, The Tim Ferriss Show. The guests range from super celebs (Jamie Foxx, Arnold Schwarzenegger, etc.) and athletes (icons of powerlifting, gymnastics, surfing, etc.) to legendary Special Operations commanders and black-market biochemists." and now he is here on Bulletproof Radio to talk about the culmination of those interviews -- his new book, Tools of Titans: The Tactics, Routines, and Habits of Billionaires, Icons, and World-Class Performers. Enjoy the show.
