Basically, I Suck

When I play Raquetball or squash I always find it easier playing against someone else than playing on my own. When I play by myself I never know which direction the ball is going to go, and it invariably goes in exactly the direction that a perfectly hit ball doesn't. So, I always lose when I play against myself. At least when I play someone else I can make a decent guess as to which direction the ball will go. Logically, therefore, I should always win when I play against someone else as they will have no idea which direction the ball is going to go, and I am always good enough to beat myself. But for some reason, even though the logic is impeccable, whenever I play against someone else, I lose. I blame the ancient Greek Philosophers like Plato and his so called theories of logic. They must have been pretty dumb if they can't figure out a simple logic problem like this.
