Well now not everything works for everyone. You have to pick and choose what works for you. What goals do you have? Are you wanting to be 100% off the grid or how much. Some of us may just want to be 50-75% off the grid.
Right now I'd like to be out of debt.
I think it's hard to find folks of 100% like minds. I'm not a believer in the end of the world, but I do think things may get pretty hard.
Earning a living from while being self sufficient is not easy and many aren't 100%. The Amish had to evolve into the cottage industries since Agriculture wasn't doing it. Some have evolved to drive cars or ride in them, have phones, and electricity but only for certain uses.
I can't grow everything I need but I am pro barter. I trade chicks for hay and horse manure. I can't handle horse, nor goats, nor sheepses. I'd like to but finding some one to process just chickens is not easy.
