This New York Times and Amazon best-seller contains the tactics, routines, and habits of billionaires, icons, and world-class performers. Tim Ferriss aggregated, analyzed and vetted these insights from guests of his podcasts, ranging 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. This is the ultimate notebook of high-leverage tools.
