Tim Ferriss

Timothy Ferriss (born July 20, 1977) is an American entrepreneur, investor, author, podcaster, and lifestyle guru. He is known for his ''4-Hour'' self-help book series—including ''The 4-Hour Work Week'', ''The 4-Hour Body'', and ''The 4-Hour Chef''—that focused on lifestyle optimizations, but he has since reconsidered this approach.
