IMO:

#1 thing to do BEFORE the shot is know what to do AFTER the shot. No sarcasm intended. Every yearyou seethe posts about 'hit one in the _____, what do I do now?'

So everybody, could you all please know exactly what you should do in case of a not soperfect hit before you EVER set foot in the woods?

Other than that, a very common mistake I have heard of (and made myself) is not comming to full draw as soon as you are in a blind/stand and making sure you can swing your bow in all permissable directions without obstruction.
