I have been playing for about 20yrs,studying the game ,going to pro events(watching)and practicing.Never been a big gambler.more of a tournament player.I have a pretty solid game but I keep shooting myself in the foot,I will out saftey my opponent,outbreak him, open up the table and then it happens,Everything is in place and im running out and at some point usually i will miss,or hook myself about half the time,when i survey the rack on the last few balls and i c no problems.Thats when it happens. Is there a MENTAL pre shot routine u know of to keep ur mind in the right place>?
