RE: How do you control the mental game?
I've got a mantra I repeat after I come to full draw;
"Pick a spot, breathe, float the pin, breathe, pull through the shot, breathe, sque..."
I usually either release at this point or let down. The shot either feels good or it doesn't and when it doesn't I let down.
I wish I could just go on autopilot and have everything connect, but it just doesn't work like that [for me].
