I know I need to get hangers... maybe? I've gotten rid of most of my things (misc computer components, clothes that no longer fit) but I'm 20 years old with the mental age of a 9 yr old. I had to borrow the broom from a roommate. I don't feel like an adult.
Other folks have the big stuff recommended, and I just wanted to add: rugs. Adds some color, helps dampen noise, and can hide some cabling.
