Nice story but being able to make one hard shot consistently will not make you a better player, just better at that shot.
A good player will get position for an easy shot, and most pro players will duck and play a safety.
A hustler will dare you to make the shot and bet on it, is this where you want to be with your game?
Don’t get me wrong, being able to make hard shots is important and the ability is a good tool to have in your toolbox.
Practicing it is also important as it develops good aiming and good stroke.
But if you want to be able to get better st the game and run a 9ball rack, you might want to consider a proper training with a good trainer.
