There’s a saying in medical education: “see one, do one, teach one.”
That’s a pretty good model for learning how to actually do something — as medical professionals must, and as opposed to simply adding theoretical knowledge.
In general, curiosity sends me to the library, and I’ve found that’s good as far as it goes. But I’ve also found there’s a limit: in most fields of knowledge, theory ultimately begs application.
Surgeons-in-training don’t just read textbooks. (Nor do pilots, nor lawyers, nor bankers, nor ….)
They learn by practice — and above all by teaching the others.
