"We sometimes hurt those we love because they need to be "taught a lesson," when we really want to punish. We were depressed and complained we felt bad, when in fact we were mainly asking for sympathy and attention. This odd trait of mind and emotion, this perverse wish to hide a bad motive underneath a good one, permeates human affairs from top to bottom. This subtle and elusive kind of self-righteousness can underlie the smallest act or thought. Learning daily to spot, admit, and correct these flaws is the essence of character-building and good living. An honest regret for harms done, a genuine gratitude for blessings received, and a willingness to try for better things tomorrow will be the permanent assets we shall seek."
