Transidental Meditation

Tim Ferriss, the host of "The Tim Ferriss Show" podcast and the author of several best-selling books, including "The 4-Hour Workweek" and "Tribe of Mentors," has built an entire empire around offering life-hacking advice, but when someone suggested he try meditation, he resisted for a while. He tried various forms, then eventually dove head first into doing a 10-day silent retreat, where he came face-to-face with a long-buried childhood trauma that made him re-evaluate how he cared for himself.
