I’m very lucky in that I have a good job, home, land and some strong skills. So, most of my model isn’t realistic for the majority. But anyway, I operate a small farm as a kind of side business/learning experiment to raise livestock/honey/eggs/ grow crops. As an mechanical/stationary engineer I’ve also set up a good failsafe system of temporary generators assuming my solar setup is damaged or loses functionalality. As well as plenty of resources I’ll need assuming I cant get power regardless (alt light sources, hard-core cold gear, water collection and purification, ect) I’m trained with firearms but hope I’ll never have to use them outside the range. I do a good bit of canning and live essentially out in the woods with no neighbors for about a mile in any direction. I have accumulated tools that can handle most projects that may come up (maintenence is not pretty but unbelievably important). Again i recognize my situation isn’t realistic for the majority. That said, anyone in any situation can learn basic skills like canning, sewing, self defense (armed or not) and basic structure maintenance.
