You can learn almost anything. The real question is whether you want it enough to be bad at it first.

Most skills aren't guarded secrets. The information is available. The question is almost never access — it's tolerance for the period of being bad at something, which is uncomfortable in proportion to how much you care about appearing competent.

The people I've watched learn the fastest are usually the ones with the lowest embarrassment threshold. They ask obvious questions. They show unfinished work. They say "I don't know" and then actually go find out. The ego management is the learning.

There's also something about choosing carefully what you want to be bad at. You can't be a beginner at everything simultaneously. Choosing what to learn is choosing what to be temporarily incompetent in, and that's actually a meaningful decision.
