Ami, I am no expert as you know, but I think I have stumbled on a routine that works for me... your mileage may vary and I know this isn't a purely "mental" tip, but it puts me in the right mind.

I think PBR. Posture (balanced comfortable stance) Breathing (one when I nock the arrow, one when I focus on my target, one when I draw) and Relax (start relaxed to end relaxed... bow arm is totally relaxed when standing, lifts straight up to position relaxed, and stays relaxed but locked throughout the draw/aim/release)

Then I turn it around RBP. Relax my grip and release hands/arms as I aim/aim/aim, Backtension to hold the draw and steady the sight window and pull through release, and Pause... don't drop the arm for 2 to 4 seconds after the shot.

PBR/RBP is easy for me to remember cause I used to like Pabst Blue Ribbon beer <img src=icon_smile_wink.gif border=0 align=middle>

The real breakthrough for me (I'm like you, want to control things and am too tense/stiff) was to start out with a relaxed bow arm, it seemed to take the tension out of my whole body.

A couple of other things I do are - never look back at my last shot after I drop my bow - it's out of my mind - and I acquire the target I am shooting at before the draw and never take my eyes off it until after I drop my arm after the shot.

The day I figured this out I shot over 100 arrows at a 5-spot and had 2 zeros out of all those shots - most of the rest were in the 5 ring. That was outstanding shooting for me
