hobbling about

What is it about being physically debilitated that makes you want to be so intensely productive? I think it's because we all do way more in our own minds than we do in reality. When you *can't* do the things you consider, it's way easier to consider doing them, since there's no fear you'll actually have to follow through on it.

I have a running list of things I could be doing if I could bend my knee. Somehow, I'm relatively certain that when I actually *can* bend my knee, that list will magically evaporate and I will sit around reading a book or playing WoW. Which I should be doing now, and would probably help my leg heal more, but somehow I don't. Instead I push myself to accomplish *something* with my day and end up exhausted with a grumpy leg.

Now, why can't I push myself that hard when I'm perfectly healthy and have no reason to be idling about??
