IMHO, the second you even thought about being more self-sufficient, you crossed over into homesteading; the fact that you've already done so much towards that goal, means you're there! According to the fine folks over here:
https://en.wikipedia.org/wiki/Homesteading
"Homesteading is a vernacular term for a lifestyle of self-sufficiency." and a bunch of other stuff ...
If you had just moved onto the property and into the existing home, and didn't do much else, that might be country-living; plenty of folks do that. You've both gone beyond *and* mixed in
Permaculture ...
Now, at least on the homestead side of things, start thinking about all the "systems" on your property. For example, the house generates waste (food, garbage, etc.) ... where is this going, and what is it costing you? Would chickens help? Would a
compost system reduce some of the waste, and at the same time, benefit other systems (
gardening) on the property?
In my mind, it all starts with planning, both on the homesteading side, and the
permaculture side ... develop a site plan, start putting things on it, and start seeing how it all ties together (or could). No matter where you are in the planning stage, it's not too late to do it.
And, of course, spend a gazillion hours reading this site and others. I'm only up to a bazillion, so still a ways to go ...
