About five years ago, my room used to look something like his room, only without the trash, I knew where to find my trashcan. It was just incredibly dusty and there was almost no room to walk. A friend of mine offered to help me clean it and we were busy for two days, filling seven industrial (Xtra Large) garbagebags. It felt so gooed finally being able to walk normally across my room and not having to wipe my feet to prevent all kinds of crums entering my bed.
Now I clean my room every month, dusting and vacuümcleaning, and it feels great! My room is even cleaner than the rest of the house! Mwoehahaha My only real problem is space, I've just got too much stuff, but I'm managing.
