Up bright and early, the sun is seriously hurting my eyes and head, gonna maybe get some black curtains so i can sleep during the day. I wonder whats the best arrangement for my room to promote positive and constructive energy?

Um, so I have a laptop in the workings that has two hardrives built into it, for the win. I'm trying to set up my room in such a way that will make positivity flow through it so it can handle all my negative. I'm thinking of putting something on my walls...they're white and driving me crazy. I hate white walls. So um...people who actually read these things any suggestions of what i can put on these walls since i can't paint them.
