will power and self conrol you can't allow yourself to be moving just look how it makes stuff jump out of the background. no caffine in the morning and get all of your stuff together and organized before you hit the woods. get a snack before you go. I promise you will never see as many deer if you can
't sit still they see you before you see them and then they'll be gone. sure a young deer may not notice every nowand then but the big guys will.
