Thought about 2 things...
My basketball coach in elementary school told us that he had stayed at the gym all night one time trying to miss a free throw. Even though obviously he was (and still is) full of it. However, the implication of no matter the shot one needs to practice.
The other thought was about my high school shop teacher. His left arm had been damaged by polio when he was small and it just hung by his side. However, with effort, he could use the power of his body to get the arm up enough to rest firearm on his arm to shoot. He even hunted quail and ducks and was a very good wing shot. Another student asked him one day what his favorite shot at ducks was. His reply was "swimming slowly from right to left".
