Teach self-sufficiency, which should always be a focus right but during industrial boom our society seems to practically focus individuals on developing good consumer-skills while gas-lighting about boot-straps.

I think endurance building activities like hiking, teaching them to not get grossed out by like gutting a fish or you know like other cultures they don't understand (just a curious attitude and not a perfection based one) , reward when they figure out something on their own and treat mistakes like they got an unexpected result in a forever experiment.

And, I think you have to be strong by being honest about the world, but light-hearted in terms of doing your best and making the most with what you have (mental endurance).

Basically, be like the dad from the book The Road.
