"Habits start out as off-hand remarks, magazine advertisements, friendly hints, experiments - like flimsy cobwebs with little substance. They grow with practice, layer by layer - thought on thought - fused with imagination and emotion until they become like steel cables - unbreakable. Habits are attitudes which grow from cobwebs into cables that control your everyday life. Self-discipline alone can make or break a habit. Self discipline alone can effect a permanent change in your self image and in you. Self-discipline achieves goals. Self discipline is not 'doing without,' it is 'doing within.'"
