I recently realized what the phrase, "Own enough stuff, and it starts to own you" means. The more things you buy, the more you're obligated to use them to justify paying for them. Your time isn't your own anymore ("I bought this guitar, so after work I must practice, also must figure out new SLR camera, and plan trip around new skis..."), and you're hemmed in to pursuing uses for your toys. I think there's a certain freedom to being bored.
