HELP

I need some sort of motivation! I have a test tomorrow and do not want to study for it! I've done so well so far this semester, I've gotten an A or an -A on every test I've taken so far and i really want to keep it up i just do not want to study. I have no motivation to do anything, I just want to lay in bed and do nothing... I'm not sick, I'm not even tired, I'm just in a do noting sort of mood! When I have so much that needs to be done this is not good! And I'm just using my blog to distract myself, basically i suck at life
