So do it. It is eminently possible, although it will involve actually leaving the city and physically inhabiting a strange and unfamiliar place.
Finding that place can be an incredible challenge, all by itself.
I left England, at 18, and disappeared into the British Columbia forests. I was there for two years, living completely off the land.
It is not an easy or a comfortable existence (:>
But it can be done.
I've single-handed a rotting plywood trimaran across the Pacific, for months on end.
Lived in deserts, and on sea-shores. Alone and as poor as any man in history. I'm still not dead.
Currently I own a small forest, and have a loving wife, where honesty and honour rule.
Don't ruin your life by trying to make something unworkable work.
Find something that does work.
This life you have, is the one that counts.
At least, while you're still able to live it!
