i had a lesson on thursday and it improved my game nearly 50% so i decided to enter an eight ball tournament on friday. started practicing at 4 pm and the tournament started at 8:30pm (30 minutes late). at this point i had been both practicing and playing for 4 hours. i won the first 2 matches and had no "rest time" between matches. when i got to the third match at 11 pm my brain and body seemed to just shut down. seemed to be screaming, "i can't lay anymore"! my usual play/practice is 3 or 4 hours. after 7 hours of play i just could not concentrate and lost miserably. does anyone have a method or any hints on playing hour after hour like a marahton? a nap between matches is not an option! :wink:
