I have a switch in my brain that I flip once the bow is drawn and anchored. I go from juttery and excited to post oak. What I'm thinking is that aim small miss small thought. Forget about the animal and look at where the arrow is going to exit. You can fill your pants after you shoot and loose sight of the animal.

All it really takes is one good screw-up that makes for a long track or a lost deer and you will learn to flip your switch. That is the hard way but probably pretty close to the truth.
