Something clicked for me two weeks ago after over a year of shooting with psycho triggers. It was a random thing Joel Turner said on a podcast, namely that the subconscious needs three punches for a knockout. On top of my shot process that I talk myself through, I now tell myself "Do this right" three times. Once before I draw, once as I reach anchor, queuing me to establish my back tension in the right direction, once more after I verify sight picture, and commit to pushing through the trigger.
That last time is the real killer. It locks me on my full commitment to keep pushing, keep pushing, keep pushing (Which I'm telling myself as I go). Suddenly, pop, the arrow is in flight before I can screw it up.
In order, my mental vocalization is this:
1. "Do this right, or not at all"
2. "draw and anchor" (I naturally establish my aim here as well.
3. "Do this right!"
4. "Tension in the right direction" (establishing increasing elbow pressure aimed slightly down and behind me, just like Terry's J hook)
5. "Here I go"
6. "DO THIS RIGHT!"
7. "Keep pushing, keep pushing, keep pushing" (which is the finger movement for my grip sear)
And then the arrow is gone, and I assess the shot.
But those three orders to do it right made all the difference in commitment level for me.
