Why the Same Lesson Twice Matters More Than Once

⏱️ 3 min read

Last year my friend K introduced me to a simple but powerful metaphor: protein-rich content and carb-rich content.

We were talking about podcasts, but the idea applies to every kind of media.

Protein-rich content is what you can build on. An intelligent news digest. A thoughtful interview with an expert. A deep dive into business, fitness, finance, or engineering. It isn’t the easiest or most entertaining to consume—it demands attention, and without it, it can feel like background static. But when you engage, it delivers education and long-term knowledge.

The definition of signal.

Carb-rich content is different. Celebrity interviews, comedy shows, sports events, lightweight storytelling—the kind of content designed only to entertain, to massage your brain when the battery is low. Easy to put on in the background, easy to forget.

The definition of noise.

K wasn’t being judgmental. He wasn’t “anti-carb.” Quite the opposite: he understood the bigger point. A healthy diet needs both. And so does our intellectual life.

For several years I’ve been shaping my own intellectual diet. Books and podcasts are my protein staples. Video, especially YouTube, has power, but that same power to entertain makes it dangerously distracting. Podcasts, when well made, create a high-bandwidth connection—laser-focused on content, stripped of noise.

My playlists and shelves are full of entrepreneurship, business, personal finance, nutrition, fitness, longevity, and mental health. Podcasts like Diary of a CEO, Y Combinator Startup, Huberman Lab, Hidden Brain. Books like The 4-Hour Work Week, So Good They Can’t Ignore You, Lifespan, How Not to Age.

At first, the repetition frustrated me. The same lessons, the same stories, the same protocols—each told as if new. Five years ago, when I was just beginning to consume these “proteins” more regularly, I thought of it as inefficiency. A price to pay for learning.

Now I see it differently.

Last year, at the beginning of my career transition, I was ravenous for guidance. I didn’t find the one book with the perfect answer. No podcast handed me the missing key. What worked was something subtler:

The steady drip of repetition.

Each time I heard the same principle, the same positive story, from a different voice, it sank a little deeper. No single story changed my tactics, but together they reshaped my sense of the playing field. They convinced me, quietly, that success was possible—and far more common than fear suggests.

Repetition wasn’t wasted time. It was reinforcement. Not noise, but part of the nutrition.

Now, when I hear a familiar idea, I don’t skip ahead. I let it do its work on my wiring. Each pass strengthens my resistance to fear and my openness to change.

Mainstream media thrives on negative bias, and we treat it as inevitable. But there’s a choice: just as in diet, where eating more quality protein makes it easier to cut empty carbs, feeding ourselves protein-rich ideas—repeated, reinforced—makes it easier to keep growing.
