I think there is a learning curve in the bowhunting process. Problems for me shooting at animals have more psychological and emotional components that makes shooting at an animal so different from shooting a target it is, well, another world kind of thing. It actually quite a dramatic moment when you get a chance...feeling excited, timing the shot so the animal is most vulnerable, remembering to shoot well, etc. I have been doing this thing for over half century and I still get excited, still miss and am always looking for the next opportunity. If I fail to fully concentrate on where I want the arrow to go I usually have a problem with shot placement. Same goes for when I peek and try to see where the arrow should hit without maintaining proper follow thru. I am afraid it is only something that gets better with time and you needn't beat yourself up over it. In fact, when an animal presents you with a shot there is no law that says you have to shoot. Sometimes, just being there and observing how animals behave and you "role playing" without any intent to kill can be as thrilling and exciting as making your first kill...it is certainly exciting and educational. Why deprive yourself of those experiences by hanging up your bow for the season? Get out there and hunt and if yo decide not to shoot, then don't. You have had a good time and had a chance to study your quarry. Shoot when you feel ready and rather than quitting, even for one season, get more determined to accept the challenge and figure out what is going wrong. Deer have a bad habit of jumping the string and if you are hunting from treestands I hope that you are practicing from one or at least from an elevated structure like a porch or roof. Shooting from treestands is way different than shooting from the ground. In any event, go hunting and enjoy all the other benefits that come with it. The kill is always anticlimatic for me anyway.
