The roots of interpersonal conflict are often an excessive concern for oneself, and an inability to pay attention to the needs of others. It is sad to see how often people ruin a relationship because they refuse to recognize that they could serve their own interests best by helping others achieve theirs.
— Mihaly Csikszentmihalyi, Finding Flow: The Psychology of Engagement with Everyday Life, chapter 7, “Changing the Patterns of Life”
