I think the best thinking you can do when your playing 8ball or 9ball is to imagine, that every ball is the MONEY ball when your shooting. That way you dont just WING it or shoot at the ball carelessly.
Plus i usta have the problem of trying to get the PERFECT position with the CB, when playing 9ball and would end up way outa position or having a harder shot than normal.
Now another way to think is that you still have one more ball to pot before the game is done, so you need to make the 9ball to get to the real money ball. Hence like playing 10ball as someone stated earlier.
But getting nervous is natural. But i when i am shooting good is when i shoot without FEAR ! Meaning i dont even think about missing a shot because i am either making all the shots i am taking or playing lock up safes when i dont have a shot.
