Honestly, much of it is the having done. The essence of the problem is the feeling that there is so much I *can* do, and therefore I *should* do, but I *can't* do, because there just isn't enough time.

Obviously, I'm going to have to deal with the problem other ways. (Mostly, I'm just going to have to get past this odd sense of guilt over opportunity cost.) But it's fun to dream...
