Streak,
It was one of the first things I noticed about the change in my game. People who had always had my number, specially those I didn't like, seemed to beat me from time to time even though I felt they were not the better player. Playing the balls on the table rather than your opponent is a wonderful game changing concept. Now, when the situation arises, anger and resentment take a back seat. It is a very rare occasion when a person I dislike beats me. Sometimes it is really hard to keep focus though. When it does happens, just let it go and go on to your next match. It isn't life or death. It's a game of pool!
