TG, I've really appreciated getting to know you in this forum, you can be counted on to ask the tough questions. The issues you raise in your post are those I have wondered myself...what happens after the novelty wears off and I'm stuck with everyday life? The things I am thinking about:
1) I am easily bored and need to be learning all of the time. How happy will I be without libraries and bookstores? How frustrated will I be that if I'm interested in a new sport, I can't afford to just go out and buy a bunch of gear and try it out?
2) Will I get frustrated with the rain and mud? Right
