9 Oct 2026 · 1 h 14 minYou built the life you were supposed to want. So why doesn't it feel like enough? Passion Struck is the #1 Health and Fitness podcast — and it exists to answer exactly that question. I'm John R. Miles — Navy veteran, former Fortune 50 executive, bestselling author — and I built this show because I lived the "successful but empty" version of life myself, and I wanted to find a better way. Each week, I sit down with the world's top voices in neuroscience, psychology, medicine, and elite performance — including Angela Duckworth, Susan Cain, Robert Waldinger, Daniel Amen, and Ryan Holiday — to unpack what the research tells us about purpose, connection, and resilience, and how to apply it to your own life. Fridays, I share what I'm learning directly, in solo episodes built around the same ideas. New interviews every Tuesday and Thursday. Solo episodes every Friday.

We live in a world that rewards visibility. The viral headline. The impressive title. The dramatic turnaround. The big announcement. The person who creates the most noise in the room.

22 Sep 2026 · 1 h 2 minWhat if the proof you're waiting for never comes? The apology. The promotion. The recognition. Someone finally admitting they were wrong about you. Someone finally telling you that you belong. What if you're waiting for proof that you don't actually need? After conversations with Cole Brauer and psychologist Marisa Franco, John R. Miles noticed a powerful connection between their work. Cole was to
