RE: 20 yard mental barrier
Quit shooting so much at even yardages. Go stump shooting and concentrate more on having a good time than on grouping arrows. Never shoot more than one arrow at a target when stumping. See how close you can makeone arrow hit at whatever you choose to shoot. Play around a lot with your distances, really close, really far and everything in between. You'll soon convince yourself it's not so hard after all to hit something beyond 20, or even 30 yards.
