In the impetuousness of free-will, I have seen children and adults alike refuse to make corrections based solely on their self-perception. I often quote the tribal adage, "If you want to go fast, travel alone. If you want to go far, travel together." There is wisdom in counsel. (read that somewhere in a very old book) Let us not be misled by our own self-deception.
