If It Feels Too Easy, You're Probably Not Learning

There's a comfortable illusion in reviewing things you already understand. You flip through familiar material, nod along, and feel productive. But real learning requires a degree of struggle — that mental friction is the sign that your brain is actually building new connections. If everything clicks immediately, you're operating inside your existing knowledge, not expanding it.

This doesn't mean learning should be torture. It means you should seek the zone where things are challenging but not impossible — what psychologists call "desirable difficulty." Read the chapter that confuses you, not the one you've already mastered. Attempt the problem before looking at the solution. The discomfort of not knowing is the price of genuine growth, and trying to avoid it is trying to avoid learning itself.
