Pressure is the key. I do all my training while my wife checks my browser history.I don't know if you are a hunter or not, but it definitely helps with making shots under some pressure. The more you hunt, the more you kill. The more you kill, the less pressure you feel.
There is lots of game out there besides deer, birds, rabbits, and squirrels. I've shot a few hogs (shot one a few weeks ago) and did not feel any pressure or have a "blur" when they were in close proximity. My rifle, or pistol makes me more dangerous than any critter. Even the carnivores...Still, any hunter can feel a bit of pressure under the right circumstances, dangerous or not.
My sentiment is shared by many, including Col Jeff Cooper.
