It took me 10 hours to turn my desk area from this:
I took the cabinet out of my room because the majority of the stuff in there was trash and paperwork/notes. I filed all of my papers in folders threw away all of the trash. Now that the cabinet is gone, I have a huge gap from my desk to the door. That problem can probably solved if I find some kind of cool furniture at Target or Ikea.
One of the reasons why I took so long to organize everything was because I had to think about whether I wanted to throw away something or not. I also spent some time walking down memory lane by reading old notes and looking at pictures.
