"Conflict is neither good nor bad. Properly managed, it is absolutely vital."
— Kenneth Kaye

"Every conflict we face in life is rich with positive and negative potential. It can be a source of inspiration, enlightenment, learning, transformation, and growth–or rage, fear, shame, entrapment, and resistance. The choice is not up to our opponents, but to us, and our willingness to face and work through them."
– Kenneth Cloke and Joan Goldsmith
