For a while I built entirely on top of things I didn’t understand. Frameworks, platforms, tools that did impressive work behind a clean surface — and as long as the surface behaved, I was happy to treat everything beneath it as magic. It felt efficient. Why learn what I could simply use.

The reckoning came, as it always does, when the abstraction leaked. Something broke in a way the tidy surface didn’t account for, and suddenly the magic was just a black box misbehaving, and I had no idea what was inside it. I sat there helpless, waiting and hoping, while a colleague who understood the layer below the tool quietly diagnosed it and moved on. The difference between us wasn’t talent. It was that they’d gone down a level and I hadn’t.

That was the moment I decided to always understand one layer deeper than I strictly needed to. Not all the way to the bottom — you can’t, and you don’t have to. Just one layer past comfortable. Enough that when the thing I’m using leaks, I have somewhere to stand instead of just praying it fixes itself.

Over time this turned into a rule about where to spend my learning. Tools change every few years; the layer beneath them changes far more slowly. The framework will be replaced, but the language it runs on outlasts it. The language will shift, but the fundamentals underneath move slower still. If I invest in the fast-moving surface, my knowledge expires with it. If I invest in the slow layer below, it compounds across every tool that will ever sit on top of it.

So now, when something feels like magic, I take that as a signal rather than a comfort. Magic just means there’s a mechanism I haven’t looked at yet — a thing someone built on top of something I’m fully capable of understanding. Going underneath is rarely urgent and almost always worth it.

The leverage, I’ve found, doesn’t live on the shiny surface everyone’s learning this year. It lives one quiet layer down, where things change slowly and understanding lasts.
