I've had this same problem off and on for about 2 years now, and it's caused me to miss THREE nice bucks in that time period.

This year I have really, really, really been concentrating on not letting that arrow fly until my pin is steady on the target. If it means taking an extra second or two to calm myself down before shooting, or even let the arrow down if I can't do it - so be it. The more I really focus on what it is I'm doing when I shoot rather than just getting overanxious and letting the arrow go, the better I'm shooting. I'm still not where I need to be yet, but it's getting better. It's all mind over matter really.

Also, from that thread the other day that davidmil linked to the one thing I tried that has helped already is to make a routine in my head for every time I shoot. For example I tell myself "One - draw. Two - Anchor. Three - Aim. Four - Hold. Five - Release." The more I shoot doing that sequence the more my shots are going where I want them to. Like I said, I haven't been cured overnight but the more I work on it the better it gets and the more fluid my entire shooting motion becomes.

I'm shooting tonight and Saturday with my hunting partner, then Sunday we're going to our first 3D shoot of the year. We'll see what happens.
