Try shooting with your eyes closed up close to a target butt. Then when using back tension, feel your muscles working, shot after shot. After that. In my abrupt way of putting things: "stop thinking about using back tension. stop thinking about holding still. stop thinking about which muscles to use. stop thinking about where the arrow will go. THINK ABOUT AIMING AND AIMING ONLY! The bow may or maynot go off. Be patient, it will go off. Just trust it. But you can't be thinking about anything else but aiming. (my two cents)
