I usually count to myself to get my breathing under control. Count to myself after I draw. Just sets a pattern in your mind and calms you. Also, I agree with letting deerget into your area. I usually try to enter the woods with some idea of what I am and am not willing to shoot. That hasbrought about quite a few days of just watching does from my stand and getting used to the presence of deer, because I've made forgone conclusion it's a bucks only day. This alsostops me from making rash decisions.
