Once at anchor, aim (however you do it) then keep the bow arm and the drawing back muscles active. Think about the drawing elbow beginning to move slightly rearward (back motion--rhomboid muscle--this is "Step #9--Shot Set-Up)and immediately relax the back of the drawing hand and fingers at once. Your hand will immediately slide along your face, under your ear and the thumb, if it was properly folded into your drawing hand at anchor, will end up on or near your shoulder.
This focus on this "back of the shot" will prevent or cure all kinds of ills -- physical and mental.
By the way, the bow arm, if kept properly active, won't stay "up" until after the arrow hits. To do that you can't keep it active and you will eventually have a collaspe of the bow arm inward (which is akin to bow arm creeping). The bow arm will jump slightly toward the target and fall down and to the outward side during proper follow-through.
Before I release my last thought is "thumb to the shoulder".
22,300 teachers have been taught this process -- they taught 1.916 million 4th-12th grade students this year.
This follow-through is the archery swing.
