My room is basically empty except for my bed, computer/desk, birdcage, and fan. It even has grey walls lol. This is mostly because my preferred horde is old books and they are pretty expensive so my collection is small. I also like maps, historical trinkets/artifacts, and indegenous art but I am unemployed lol.
I don’t dislike what I currently have but I do wish I had unorganized stacks of books everywhere (if only my bird would not poop on them)
You got that AUDHD too huh. I keep my room organized by having next to nothing in it lol. The only place I decorate is my desk and its mostly abandoned hobbies.
