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.
One of the reasons it has seemed so difficult for a person to change his habits, his personality, or his way of life, has been that heretofore nearly all efforts at change have been directed to the circumference of the self, so to speak, rather than to the center.
Our self-image and our habits tend to go together. Change one and you will automatically change the other.
