There are a number of reason we become unhappy with shooting. Most of us can relate to the feeling. Personally, I shoot better when I routinely practice form by shooting without a target. Shooting for form, should be fairly close and follow a routine you establish. Secondly, one day rest for any time you shoot more than 30 min. If you go to a gym and workout for 30 min. on upper body, or cardio, you probably want to switch to something else the next day. Unfortunately, you can't do that with shooting, because your using the same muscle groups. Finally, do not shoot if you are unhappy with your results. Practicing should be fun, relaxing and not a session of practicing bad habits. Practice when your interest is high, not low.
