Need help figuring out my personality, I feel like I'm a walking contradiction?

Let me explain what I mean by this, I feel that whatever outside stimulus or events would lead to one event occurring, I'm more inclined to produce basically the exact opposite. Here's a few examples, one way is when I've been studying for the exam to go into law school, I always took the practice tests under conditions that I was fresh and ready but my scores weren't very good. I started taking them when I was tired out and shouldn't be as focused and they skyrocketed. Another situation is whenever I would listen to music that should get you up and going, I would become more passive and less aggressive in the sport I was playing. I tested my theory by listening to calming music, things like Disney soundtracks even, before games. Naturally I felt more focused when I was in games and brought a much higher level of intensity. Can somebody explain what this tells about me? I seriously don't get it.
