Roscoe gives you good advice. If it's not time to shoot you can also close your eyes when you're breathing. Slow thoughts of breathing and taking your mind off the deer for a few seconds. GMMAT also has it pretty much down from the rookie end. LOL It gets easier for sure. I see people all the time say that the day they stop shaking and getting nervouse they'll give up bow hunting. I say to that.... BULL HOCKEY!!! It's all about becoming the predator. It's all about becoming the tree. It's all about becoming invisible. It's all about becoming the ARROW. I really don't become nervous with a deer. I'm more nervous with a half dozen people watching. When I'm in the tree it's me and the arrow and the deer. I really don't get nervous anymore. That doesn't mean I don't enjoy the heck out of it or enjoy it any less than someone else. I enjoy the hunt and becoming the arrow.
