I don't think being a minimalist means limiting yourself to a certain number of things. I know I have less than 100 things, I don't bother counting, but I really don't have much. I did simplify everything, and I own very little. I did this because everything you own has to be fixed and cared for. If you own less things, you have more time for yourself. You also don't feel stuck in one area when you can throw your crap in your car and be gone in 20 minutes.
I know exactly how you feel. I looked forward to having a few beers and playing computer games when I got home, it was fun for about 3 days. Fortunately, I can frequently go hiking where I live, it is short trails and not really the same, but it is something at least. I think about the AT a lot.
