Ina,
Most important is to learn skills, how to fish, hunt, trap, garden, dress an animal, make fire, etc.. Simple things to, like if you don't know how to drive, learn to drive, learn to patch a tire, take a self defense class etc.
Next sum up your situation, what is my intent in a real emergency (stay or go), is staying or going possible, where do I go, how will I travel, what will I need, what is between me and where I plan to go etc. If I plan to stay, how will I cook, dispose of human waste, protect my domicile etc. In a grid down situation no water, no toilets, no refrigeration, lack of law enforcement response etc...
Next make a kit list of what you will need to survive, not to be comfortable but SURVIVE - food, water, shelter, navigation, protection, fire etc.
- One list for what you can carry (my life-line bag I cant lose track of)
- Another list of things in your auto or what you would put on your bicycle or what every your mode of transportation is where you live, Metro, trains, bus etc should not be expected to be operational. These items are important but losing them in a riot or encounter with hostile people will not be an end to you i.e. the life-line bag.
Lastly, start assembling your kit, this does not mean large amounts of money, use dollar/pound stores, thrift shops, pawn shops, garage sales etc. Most my kit has been assembled by people who saw no use for an item.
One thing that so many people forget is HEALTH. Get in shape, stay in shape, live health. their is no use in prepping if you can't carry your kit or can't walk the distance you need to go to be in a safe zone. You quickly become a victim vice a survivor.
I do not believe in zombies etc. I prep for civil unrest, catastrophic weather and natural disasters, etc.
