I'd be lying if I said I was even the least bit organized. I still haven't found that bowl of spaghetti I lost track of in November.
I can usually find what I'm looking for, though, because I classify all my stuff into one of two categories: important stuff and not important stuff. The important stuff (the TV remote, laptop computer, chocolate stash, Legos, etc...) is all on or near my futon. All the not important stuff (school textbooks, for example) is somewhere in the rest of my room.
