Joel is a fantasic guy and he will help you. I havent bought anything except his first dvd and have spoken with him afterwards. The mantra is the key for me and learning shot discipline. It is hard when under pressure but Im learning every day. I very rarely shoot a shot that wasnt at full draw. The key for me has been not even beginning my mantra until im at anchor. My mantra is ANCHOR- HOLD ( the hold is also the time when Im focusing on the spot and deciding whether or not to release) and then RELEASE. The thing that clicked for me in his first video was "quit slowly drawing the bow, get back to anchor like you used to when you shot wheels". It was like a lightswitch.
I still mess up and Ill battle this forever, but Im beating it normally.
