"Everything is deception: seeking the minimum of illusion, keeping within the ordinary limitations, seeking the maximum. In the first case one cheats the Good, by trying to make it too easy for oneself to get it, and the Evil by imposing all too unfavorable conditions of warfare on it. In the second case one cheats the Good by keeping as aloof from it as possible, and the Evil by hoping to make it powerless through intensifying it to the utmost." ~Franz Kafka

"The excessive increase of anything often causes a reaction in the opposite direction." ~ Plato

"Our children evaluate themselves based on the opinions we have of them. When we use harsh words, biting comments, and a sarcastic tone of voice, we plant the seeds of self-doubt in their developing minds.... Children who receive a steady diet of these types of messages end up feeling powerless, inadequate, and unimportant. They start to believe that they are bad, and that they can never do enough." ~Stephanie Martson

"Do not allow yourself to waste energy where it isn't deserved. Effective anger management is a tried and true stress reducer." ~Patrick Allen Johnston
