I would say just take it out on a day when you don't really care if you take a deer or not. Just pick a day, or week, and say "I'm gonna try it". Doesn't have to be the best week of the year, the peak of the rut or anything like that. While your out there, do some stuff you wouldn't do normally. Take a Judo with you, shoot some leaves or mushrooms. Hunt from the ground. (Tradbows are great for this). See if you aren't enjoying the hunt more than you're missing the kill. If you are, you will want to do it more. If not, get the compound back out and climb a tree.
