This sounds like normal burnout to me too. Happens to everyone. It means you're not enjoying yourself anymore--you're not enjoying playing the game. So, I will give you the same advice I use for myself when I am not having fun playing pool competitively for money anymore. Play the game simply for the enjoyment you get from playing it well. In other words, forget about the outcome--the bottom line is not the point. To play the game well and enjoy the beauty of doing that is what the game is about. If you are in the game for the beauty and enjoyment of playing it well, and of continually learning and improving in the process, then you will not be bored, you can fade the bad beats, and the winning will take care of itself.
