My answer to this dliemma was self-discipline. I figured I could just make myself do good things, think good thoughts about other people, but that was no easier than walking up to a complete stranger and falling in love with them. I could go through the motions for a while, but sooner or later my heart would testify to its true love: darkness. Then I would get up and try again. The cycle was dehumanizing.
