CastroEric is the host of The One You Feed, a podcast with over 500 million downloads.
Eric Zimmer launched The One You Feed podcast in 2014 with no audience, no name recognition, and a podcast name that took explaining. Twelve years, 850+ episodes, and 500 million downloads later, he released his first book — How a Little Becomes a Lot — a title that is, in every way, the story of his life. In this conversation, we talk about how incremental progress actually works, why you can't see it happening in real time, and why that's actually fine.
We also go deep on the business reality of podcasting in 2026 — the early mover advantage is gone, ad CPMs are harder to sustain, and Eric is actively pivoting from reaching many people loosely to serving fewer people more deeply. Then we spend a lot of time in the weeds of the book publishing process: the six-month proposal, the 18 months of writing in half-day increments, the uncomfortable dance between your vision and what an agent and publisher think will sell, and the emotional work of promotion — watching who shows up and who doesn't, and applying his own frameworks to keep from spiraling. This one got personal. I'm in month 11 of my own book proposal, and Eric helped me see the other side of a process that has genuinely been shaking my confidence.
