Games/School/PastLife and 2 guys in my head

This is becoming annoying: Every time I start to study for something my head comes up with a million things to distract me. I am in my room, it will make me go to my computer for something. For instance, this blogg post is made while I was studying and thinking how my head makes me do things beside studying.
If I am in the library or somewhere else, I would start imagining things, making up stories and scenarios. Sometimes I come up with some interesting stuff (look at the previous post) and sometimes they are just a waist of time. Wish I could smack my head/imagination but I sort of need them :)
