Living off the grid would be living with no paper trail, no social security number, no bills, no credit, no record of you or your existence on paper anywhere including in digital form, the internet. It's a bit impossible to truly live off the grid. Some do it though.
Self sufficiency would be generating your own power, obtaining your own water, living off the land, raising livestock, etc. You can still have the internet and all, but you don't need to buy anything to survive.
Prepping is building bunkers, collecting guns and ammo, stocking up on emergency food, etc. You at least have a means of being self sufficient if needed, growing food and what not.
At least that's how I see it.
Yeah, that's pretty accurate the way I see it too.
Most people are oblivious to how much of a paper trail they leave behind.
If someone wants to find you bad enough, there are ways to locate you.
Unless you go off-the-grid.
Even if you lose the credit cards and pay for everything in cash, there are still cameras all over the place that can track your movements. Plus, with the advent of facial recognition software, just being in a public place puts you back on the grid.
Many 'preppers' think that stockpiling supplies is prepping.
I disagree with that idea.
When SHTF, the best prep will be to know where things are located and how to use them. What happens when your stockpile runs out? Knowing which plants in your area are edible and how to plant edible crops will assure your survival. Stockpiles and bug-outs are nice but in a true scenario, they may not be accessible, then what will you do?
Knowledge is the best prep.
