SUBSCRIBE to the 10% Happier Podcast for more breakthroughs in mental health and productivity. In this deep-dive conversation, Tim Ferriss returns to 10% Happier to answer a deceptively simple question: "How are you?" His answer leads us into the frontiers of mental health treatment, including the Saint Protocol (Accelerated Transcranial Magnetic Stimulation), the emerging field of Metabolic Psychiatry, and the critical importance of social relationships over self-help isolation. Tim also opens up about his upcoming project, "The Notebook" (co-authored with Neil Strauss), which focuses on the essential skill of saying "no." He shares the "Life Tetris" strategy for declining invitations, how to build a "Benevolent Phalanx" to protect your time, and why he is creating the card game "Coyote" with Exploding Kittens to prioritize play over work. Whether you are interested in the neuroscience of neuroplasticity, the benefits of the ketogenic diet for mental health, or just need practical tools to stop "promiscuous overcommitment," this episode is packed with actionable insights. In This Episode, We Cover: • The "1-Day" Reset: How Tim used Accelerated TMS (Saint Protocol) combined with D-Cycloserine (an old antibiotic) to treat OCD and anxiety loops, compressing months of therapy into a single day. • Metabolic Psychiatry: Why Tim believes intermittent ketosis and metabolic health are the next frontier for treating psychiatric disorders, referencing Dr. Chris Palmer’s Brain Energy. • The Trap of Self-Help: Why "working on yourself" can lead to isolation and how to use relationships as a counterbalance. • The Art of Saying No: Strategies from his upcoming book, including the "Life Tetris" excuse and how to avoid the "void" that leads to saying yes. • Health Span Optimization: Tim’s current approach to longevity, inspired by Peter Attia’s Outlive, including time-restricted feeding and lipid management. • The "Coyote" Game: How Tim’s new card game with Exploding Kittens teaches high-stakes bluffing and laughter.
