Start with small, achievable steps. Trying to get to 100% ready quickly is overwhelming.
If you don’t have a gun, buy one. Then train with it.
If you don’t have food storage, buy a chest freezer. Get a 1/4 cow from a local farmer. Buy a few extra non perishables every time you go to the store. Buy extra water bottles.
Buy a small generator, basically enough to keep your appliances running.
