In other news, I played in the pool tournament at the Mercury last night. Lost in my first game. Didn't play well at all. Haven't been playing well since Christmas.
I am going to stop playing for a while. Stop beating my head on a wall. In two or three months, I'll try again and see if my headspace has improved enough.
I should point out that the reason I am not playing well is that I just can't focus when playing. So I miss the fundamentals of good billiard form and consequently miss my shots. It's a headspace issue, not a skill issue.
