I learned how to shoot from a person at the pro shop that I went to. I have a kind of mental checklist that I go through when I shoot

1 draw back and anchor with my thumb on the back of my neck
2.turn my forearm out away from the bow and loosen my hand that holds the grip so that only the crock of your hand is holding the bow, the wrist sling is very important.
3. start by aiming your pin at the top of the target and slowly work your way down while squessing the trigger on the realease
4.keep your hand completely loose at the shot, and hold the bow completely still
until the arrow hits the target

good luck shooting
