Tim Ferriss: Experiments in Productivity, Learning, and Lifestyle Design

Tim Ferriss is an entrepreneur, investor, and author whose books and long-form interviews popularized systematic experimentation for work and life. Known for The 4-Hour Workweek, The 4-Hour Body, and Tools of Titans, he distills tactics from elite performers across technology, sports, art, and science.

Ferriss advocates testing assumptions through small, reversible bets; designing processes that scale; and cultivating meta-skills such as accelerated learning, habit design, and selective focus. His podcast has documented thousands of hours of practical wisdom from world-class guests.

Beyond optimization, Ferriss supports science and mental health initiatives, highlighting the value of self-knowledge, community, and purpose in a well-designed life.
