An excerpt from the book Positive Discipline by Dr. Jane Nelsen.

Where did we ever get the crazy idea that to make children do better, first we have to make them feel worse?

Think of the last time you felt humiliated or treated unfairly. Did you feel like cooperating or doing better?

Take time to close your eyes and remember a recent time (or a time during your childhood) when someone tried to motivate you to do better by trying to make you feel bad. Remember exactly what happened. Get in touch with how you felt. Be aware of what you were deciding about yourself, about the other person, and about what to do in the future. (Even though you were not aware that you were making decisions at the time.)
