You have to relax and let it happen, i still am not great but have gotten better just let the ball roll and hook happen with the right ball in my hands for the shot. I am big guy 5' 10" 250lbs fat you could say but very powerful, so for me with my muscle mass and size it is hard to just let it happen. Like Kevin Costner says in the baseball movie clear the mechanism, people talk to me on the approach and yell at me but i tune them out and just go. I tune out thinking about poeple watching me and just look at my feet first get lined up,spot the target and then go works everytime. If i think about what i need score wise i pull the ball, push the ball or just miss my mark by 2 boards so for me the key is do not let it get in your head and you will be better today. I also feed off of trash talk which bowling scratch leagues are great too help you focus on stuffing a shot down your foes throat, i prefer to bowl a guy who averages me about 10 pins it makes me step up for the night. So keep calm and relaxed and it will come to you coaching will help but do not be afraid to switch to a coach who is right for you. Also never ask advice of other bowlers in mid league it will screw you and most opponents love to screw up the other team and sit back and laugh. Just a couple of thoughts-barry
