Patience and calm helped me. I knew I was good enough for a decent run at 9 ball run to 7 or whatever. Harnessing one's emotions is difficult. I'd get down and it would make matters worse affecting my usually loose personality. It would eat at me for hours after. 1st of all it's important to realize there are lots of players better than ourselves. And even at times we lose to a lesser player. The important message is to concentrate on each match, breathe easily and relax. Do not hold the cue when not shooting, do not waste thinking about what the opponent is doing, save mental strength for when you arrive at the table, sit, let arms hang limp, no negative thoughts. Isolate game problems and work on them with targeted practices. When irritated after a match trick the mind. Think of something nice in your life. There's always another game.
Thank you for your feed back and for keeping on track with the topic, not sure what the last two were about.
I think for me this extends past pool so it could be harder to "fix" than normal or expected. The first thing that i am going to try and do is to continuously view myself as my everyday competition speed and not my practice speed. The hope is to reduce expectations on myself with a false sense of ability, this should make me accept my errors more and thus reducing the whole "I'm a failure" emotional thing.
