You can make yourself feel better about yourself if you project your shadow side, if you project your own potential for evil onto someone else. By annihilating them and, therefore, your shadow, you bring yourself into some state of purity or reformation.
As I said this year, I didn't try to put any pressure on me by setting high goals or anything, I just want to make sure that every single time I'm out there on the court I do my best, I give 100%, and see where it's going to end up next year.
