I grant I learned all of those things, but I think pretty well everyone learns those things by adulthood, and I don't think my forgetting a language especially honed my understanding of those points.

I don't even know if you're arguing in good faith, because your second dot point isn't really a thing that even a child needs to learn.

I'll also thank you not to suggest that our differences of opinion are due to your superior understanding of my upbringing.

I agree...I think those are things we're culturally taught, typically implicitly and not explicitly.

And I don't assume to have an understanding of your upbringing. That's why I was posing it all as questions. The points I made are things I think can potentially hinder learning and are commonplace in society.

You ultimately have to want the skill. The gp would have noticed his skill gradually waning, not suddenly when it had gone, yet as a kid he didn't care for it.

How would you notice a skill waning if you aren't using it at the time?

You're right, I don't know what actual skill I had in mind there (one are you are no longer trained in but still use). I meant to say, even when a kid is wise to the danger of not taking lessons, they don't know what subjects are best for them or how many different ones must be pursued.

I think the key is to teach them a way to integrate whatever they learn into a joyful life that strives to contribute to all other life.

Teach them to tap into intuition, ask (not demand) for help when support is needed, and learn how to learn.
