À propos de cet audio

 Tim Ferriss is a self-experimenter and bestselling author, best known for The 4-Hour Workweek, which has been translated into 40+ languages. Newsweek calls him "the world's best human guinea pig," and The New York Times calls him "a cross between Jack Welch and a Buddhist monk." In this show, he deconstructs world-class performers from eclectic areas (investing, chess, pro sports, etc.), digging deep to find the tools, tactics, and tricks that listeners can use.© 2014–2021 Tim Ferriss Gestion et leadership Économie
