Well, I am more smart than cult but really neither. Common sense, proven methods and learned form other goes a long way but, intuition has a place too. I do live in a rural location and, we are as self sufficient as is practical given the land we have and the location.
Our food does fine with minimal care, the animals of course need at least a daily check and some more attention than that but, that takes less than 30 minutes a day.
I didn't start out intending on going to permaculture, I started out wanting to be a self sufficient as possible and, wanting to get the various chemicals and other garbage out of my food. Being lazy at heart, I simply found the least labor intensive ways of doing that, and being a cheap skate, chose native and heirloom or, at the least no hybrid plants so I could replant them as needed. I chose animals that required minimal to no vet care, could eat what I could grow, hunt or, fish for to save money.
Of course everything had to be suitable for my zone, and thrive here. Pretty useless if I have to go to extremes to keep it alive or get anything useful from it.
Yes it turned out to be permaculture but, I did not have even the term in my head when I started, I just wanted as natural and self sufficient a life as I could create for myself and my family with the minimum cost and work involved - I don't want to have things that need doing and I can't do as far as day to day living and getting my food when I'm 80 or 90 and, I'm not going to spend a small fortune doing it.
