One thing I've learned from being in Japan is that it doesn't often do me much good to predict how I'll feel at a given point in the future. I thought not being home for Thanksgiving would totally bum me out, but I was okay. I thought buying a Nintendo DS would provide me with hour upon hour of gaming pleasure, but really it hasn't had nearly that impact. I thought having a car would merely be convenient; now I can't imagine what I'd do without one. I'd like to get a minidisk player for my car, but I have a feeling I'd soon adjust to that, too, and no longer appreciate it so much.
What's nice is that according to this article, I'm not alone.
