Fantastic points that everyone mentioned.
Most beginners go overboard with weapons, food, panic buying.
I would really want to highlight the point of “panic buying”. Once you realize that the floor under your feet can break away any second this can easily happen to a lot of people (and a lot of companies cash in on that). First I would say is take a step back and learn. Do research as if you would start a new hobby and make sure you know how to spend your resources wisely or you end up with a lot of crap you throw away sooner or later.
That’s why Im a big fan of food rotation and not much into the freeze dried food for a whole year idea, that is of course unless you eat them like regular food as well.
