Change one and you will automatically change the other.
Our habits are literally garments worn by our personalities. They are not accidental, or happenstance. We have them because they fit us. They are consistent with our self-image and our entire personality pattern. When we consciously and deliberately develop new and better habits, our self-image tends to outgrow the old habits and grow into the new pattern.
The pianist does not decide which keys to strike. The dancer does not decide which foot to move where. The reaction is automatic and unthinking. These habits can be modified, changed, or reversed simply by taking the trouble to make a conscious decision and then by practicing or "acting out" the new response or behavior. The pianist can consciously decide to strike a different key, if he chooses. The dancer can consciously decide to learn a new step and there is no agony about it. It does require constant watchfulness and practice until the new behavior pattern is thoroughly learned.
An explanation by Maxwell Maltz in his book "Psycho-Cybernetics" about the importance of keeping an eye on our habits.
