“ Anger is good... Anger, you see, is to people what fuel is to an automobile. Without it, we would not be motivated to rise to any challenge, and life would be no more than mere existence. Anger is an energy that compels us to define what is right and wrong, good and bad, just and unjust.Anger is also like electricity. Electricity is powerful-- so powerful, in fact, that it can cause devastating destruction if it is mishandled or abused. But if channeled properly and intelligently, it is highly useful to mankind. ”
