Fighter pilots and commercial airline pilots are tested and trained to follow procedure no matter what the circumstance. They are habitually conditioned by their instructors to practice specific routines over and over again during training so that when a circumstance does occur, they waste no time judging the scenario.
You see, when you judge a scenario emotion is quick to follow. And when unnecessary emotion is present, it can hinder your ability to follow through and create your desired result.
A perfect example of this is to imagine a pilot flying his plane in a densely foggy area surrounded by mountains. The pilot has lost all function of his aviation instruments and is virtually blind. Making one wrong turn would send both himself and his plane crashing into the side of a mountain.
Faced with a stressful circumstance the pilot though does not panic. He has been trained and conditioned hundreds of times before he ever got his license to maneuver through this type of circumstance. He radios in traffic control and in tandem adjusts his altitude and direction based on the GPS that traffic control is seeing. He habitually and calmly steers the plane and makes it through the fog unharmed.
If the pilot had not been trained in this scenario, emotion would have flooded his head. Fear, doubt and overwhelm would have clouded his judgement and lessened his chances of surviving the difficult circumstance.
Be the fighter pilot of your life and decide ahead of time how you are going to maneuver through unexpected circumstances. Once you have decided, then train yourself on it. The practice of following a preset routine is literally the formation of a new neural pathway (behavior) that will be much easier to execute when faced against a stressful circumstance and emotion.
