Determinations and focus make us a street animal capable of protecting us. It is like fighting. If someone punches us a little we try to ignore it. I'm a creative fellow but it is hard to find a way to create strong aggressive emotions by facing a target. Don't be distracted by concerns that may take away from your ability to shoot.
Nothing beats determination to accomplish a goal.
Once a shooter focuses or concentrates on the target the performance level will rise accordingly. As she saw each shot hit home she smiled, giggled and then laughed. It made her focus on the target and she forgot that others were present and watching. Next time you are at the range try to HATE your target. You might find your performance increasing and feeling a whole lot better when it is over.
