More shots are missed by not picking a spot. the best shots at targets with a dot or circle will miss a animal if they can't pick a small patch of hair or a small spot on a animal. That and concentration are very important.

You could be "trying too hard". It so consumes you that the slightest fault is magnified a thousand times. Then shooting is less fun becoming instead an obsessive work to get back on track. You wouldn't give a second thought if asked to throw a baseball regardless the distance up to a certain point. Archery is the same. Have fun. Don't be so critical. I've even seen Byron miss a time or two and he's the best shot alive.
