Even in Kyoto

Eh, I wouldn't swewat the whole self reliance thing too much. People all alone in the middle of nowhere have to know an awful lot just to subsist, and none of it's taught in school these days. Survival, knowing how to hunt and find food... Agriculture, blacksmithing to make tools, etc, etc. It's too hard to make it on your own.

I suppose if you knew enough to go out and hunt down enough animal food you could get by while you hunted down a seed crop, chopped down a tree with a rock to make a fire to melt iron ore (gotta find the ore, too) to make tools to kill other animals to make leather to tie more animals to plows so that you can plant the first crop, so that you have something to eat after you gather more ore to make more tools to work the wood you'd have to chop down to make a house with.

Of course, if you want to go the vegetarian route, you'd have to establish a broad enough teritory full of wild food to eat while you planted enough hemp to make the ropes to tie the animals to the wooden plows you'd have to shape with rocks. Then when winter was over, you could start growing food the next year.

I dunno. I think you should open up the coffee shop so you have a decent job while you go to school. :) Then when you need a place to be alone you can close up and have coffee.
