Totally agree with KOxxx..."Frugalty is the heart of self sufficency " like he said, the less we can do with now, the better off one will be when the poop hits the fan. Theres only one light on at a time in my house, thats whereever i happen to be at any given time.( wife passed and children grown and gone) so home alone most of the time..I shop new food sales every Fri. morning religiously, save alot..!Since here on eastern Long Is. ny its difficult to find work, i barter.I work a few hours a week for chicken feed, feeds my hens and me eggs, sell surplus.
Huge garden, have over 3000 heads of organic garlic growing now, sell out of chicken farm store.Have heated fo over 30 yrs with wood, saved thousands and thousads of dollars not buying fuel oil for heating.I do use heating oil for hot water, but not much.I cook often on hot ember's in my woodstove in cast iron..You get the picture,i have to live frugally, i poor...I'm pushing 60ryrs, can't fish commercially like i use to for a couple decades, very hard work.So i've learned ow t survive doing what i can, and each year its more of a challenge..! I fish and clam locally . make a kick ass white clam sauce...lol No retirement IRA or health Ins. I know what frugal means, and can't wait to turn 62 for medicare,social secruity, etc.( if theres anything left) I'll be high on the hog then..!Yep, its a good thing to know how to live with as little as possible, that way, you can't miss what haven't had.But it certainly doesn't mean you can't live and eat well.
It's mostly a state of mind,and knowing how to use what mother nature has provided for us to use. I feel well prepared.I know where to go in the wld to eat.I'm grateful i live in an area where i can survive mostly on seafood if i had t

f course i love seafood and eat it often anyway.So these are all thing people can do where they live to survive.The city is different, tougher..but you can still do alot.Rooftop beehives( YES, many in NYC), honey is healthy and great for bartering.A small garden patch, weekly emergency food storage, bit by bit..Ever place has its own ways, but the princples are the same, be it country or city...SS is an awareness, and acting on that awareness...
