I suppose it would be mostly practical skills, cooking, fixing things. Usually had to be done by people themselves.
Maybe also mental things like navigating (with or without paper map) and remembering their daily and weekly agendas.
What other things would be a big difference with the people today?
It sounds like you are better at it than most kids these days. I look up solutions all the time. No sense reinventing the wheel. I’ve also spent days on some problem without looking elsewhere for a solution. The dopamine from solving a problem myself is excellent.
