> There's no substitute for experience here. It's also a very transferable skill so it's one that used to be taught in schools but no longer is.

This 100% should be taught in school, it would have been one of the most useful things I could have learned.

When I was in school (in seventies), all boys at least tried to learn how to use and take care of all sharp tools and machines with one up to wood and metal lathe. When I was in school now as a teacher, scissors were the only somewhat sharp things kids were allowed to use. Risk tolerance is so low in our society nowadays, sense of responsibility of children is nonexistent etc.
