I desire to be "SS"....but seriously....I don't think any one can be totally self sufficient. I still want my internet, and need my microwave. I drive my pick-up truck. I need the ingredients to make soaps, or buy them already made. I will color my hair as long as possible.....
Now, as far as reduce/reuse/recycle....I have done that forever. My dad is very frugal, although my mom was the "spendy" one. I never cared much for that ..spend, charge, debt cycle.
I washed my babies cloth diapers..all 3 of them...90 diapers a week. I nursed them all too...as long as I could. I went to LLL meetings, and learned more. Made my own baby foods. Hung out laundry. Reuse grocery sacks, both paper and plastic.
Nowadays....I conserve my driving, as I am un-employed. I was laid off back in 09, and jobs are non-existent. We have 1 acre and are growing veggies, and I have started to grow herbs. We have just gotten chickens, to raise for eggs and meat. Bought 1/2 cow for beef, and buy in bulk anything we can freeze and 2 of us can eat. We don't have cable tv...or landlines. We have 1 cell phone contract, with the multiple phones. Bought the property with house as a bank forclosure...dang good price.

Both vehicles are paid for, and mine is a 98. Fiances is a 2004, I think. I get the cheapest auto insurance I can, and every discount available.
Fiance and I are pretty frugal...as much as possible..given the fact that he still has to drive to work 35 miles, one way. But at least, he still has a job. The same one, for 13 yrs now.
The most recent "frugal recycle" project.....their shop.....machinist shop...gets copper from France. Some customer order. Not a lot, not weekly, but enough. Fiance gets the pine shipping crates from his boss, brings them home....cleans them up, cuts them down, and he makes all sorts of wooden things, from them. The latest, the chicken tractors. And, a lovely potting bench for my hot house. That itself has brought the price of the chicken tractors down tremendously...as well as keeping them lightweight. I am only 5'2"...so, anything too heavy, I can't move.
