Well, first of all, start watching Hoarders, Buried Alive and then you'll be all like "Oh, I don't want to live that way!" and then that will get you in the mood to clean and organize. Maybe buy cheap file folders you can hang on your wall and start put important stuff in those. Every Friday, I clean out my folders from school, then I feel relived. I would suggest buying magnet boards, (May be expensive) and hanging them on your walls too. They look awesome too. If your unorganized with schedules and stuff, I'm out of things to tell you. Hope this helps!
