What are some organization tips for a 13 year old girl?

I know the biggest thing that helped me, especially in college, was getting a day planner. I know it sounds lame...but they have some super cute ones and they really help you write what you need to do and what's going on. When you get home, simply look at it and cross things off as you finish them. It'll help you remember your homework, projects, and about anything else you need to remember for the day. Also, get a small work space where you can do your work, and keep it there. Constantly having to move your work can be a pain and stressful, also make you more prone to lose things. Also, if you're talking about going the extra mile, maybe getting some storage space if you need some for clothes on the ground, etc.
