I have never heard anybody say shooting well instinctively was easy, quite the opposite. I shot for about 30 years before I even knew You had to have an aiming method to hit the target. I enjoyed shooting all that time and was even pretty good at it, pretty successful hunter too. I have always shot instinctively for enjoyment. If hitting the target every time was my only interest, I would put sights on my bow or choose a different hobby. That being said, I strive for accuracy and good form, and both can be attained while not using a specific aiming method. I believe everyone should shoot how they like and enjoy it.
