Don't think evenabout the last 3-4 critters. They are ancient history. Over and done with. Nothing you can do about them. The only shot thatmattersis the next one.
Don't even think about it being a deer. Picture a bullseye right behind the shoulder (actually, I alwaysvisualized my boss'sface and aimed right between his eyes

) and let yourself execute the shot.
You'll be okay.
