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.
There are some great suggestions here but I wouldn’t sweat it too much, this looks pretty average for 20 yo.
I can recommend trying different layouts from time to time. You can always change it back and it helps keep things fresh (also mentally).
If you want a step up in responsibility then get an easy plant that’s suited for the light from the window.
