Obsession

Lately I have been reflecting upon my behavior and the one thought that I keep wondering about is, how did I become so obsessive? How did I get to the point where I actually believe that if I wear the right shirt my team will win? As I have grown older this behavior has mellowed a bit but I still believe that I have jerseys, hats, and tshirts that have magical powers that when worn will affect the outcome of the game. How does an educated person, with a degree in psychology, get to this point? I know there are other people out there like this but I still can't figure out how people get caught up in this type of thinking.
