As the old Indian said, "Walk little, see lot."
Pay attention to the little things while you are out there: Watch a spider build a web. Watch a fox hunt mice. Enjoy the whole experience of being a part of nature and of being a predator. That way, every hunt is productive whether you take a shot or not.
And, get one of those little puff bottles with powder in it and use it to check the wind often. That will tip the odds in your favor. It is amazing how much the wind moves before a person can feel it.
