Take the sight off your bow. Stand 10 to 15 feet in front of a hay bale without a target on it. Shoot a dozen arrows into the bale, focusing only on proper form and not on where your arrows hit. Repeat for three to four sessions.
Install the sight. Stand 10 to 15 feet from the same targetless bale. Pick an imaginary spot to shoot at. Don't try to hold the sight pin dead still on the spot; rather, let the pin "float" over it. Shoot a dozen arrows this way and repeat for three or four sessions.
Have a friend stand behind you, watching carefully. Now shoot several arrows with your shirt off (women can wear a sports bra). Your buddy should see the shoulder blade of your release arm moving toward your spine after you hit full draw.
Once you've mastered proper form, begin shooting at a 3-D animal target. Ignore any marked bull's-eyes or vital zones. Decide on an acceptable "kill" area and strive to put your shots within it. Concentrate on form and let your sight pin float on the kill zone; your arrows will follow.
