Definitely wouldn't have to worry about growing the very strong smelling strains!

Definitely look into college, if not for a degree then just for individual classes to learn about stuff...
Agriculture and/or horticulture, plumbing, electrician type stuff, auto mechanics, first aid, etc.

And learning different ways to generate your own electricity...

Even take some courses somewhere to learn about the natural vegetation and herbs, how to use them... some outdoor survival classes would teach you some of that stuff, as well as hunting. check it out.

There's a lot to learn about being truely self-sufficient, sadly we're not taught much of that through school or from our parents. They want us to work then so-called 9 to 5, make money... money money money... taxes, rules, etc. I know you want a simple free life, but you'll have to work hard for it as well... It's just that when you succeed, you should be much more rewarded from your efforts.
