Jonathan Haidt in his book, “The Happiness Hypothesis” (New York: Basic Books, 2006), makes the compelling argument, drawing from the school of positive psychology, that virtue enhances happiness. Virtue, in this case, is defined broadly as excellence and involves morality. A leader who can cast the actions of the group as serving a noble cause can increase the group's level of happiness, and in this virtue-inspired happy state the group will be further motivated to work toward the virtuous goal. The shared sense of a virtuous mission creates a shared identity, and the competitive, proud sense that they will excel in achieving that mission.
We in the medical world have little problem believing that we have a virtuous mission. Let us continue to work as a team within our groups, institutions, specialty, and in the broader role we have in society to use our talents creatively and cooperatively so as to continue advancing our mission for neurologic health.
