The height of personal happiness can only be measured by the depth of personal sadness. Happiness is not a stand-alone feeling. Happiness is a comparative emotion. The measure of happiness a person feels is judged against the measure of sadness a person felt in the past. The greater degree of sadness, the greater degree of happiness. Without sadness, happiness has no meaning. Ironically, the fear of emotional sadness often restricts a person’s ability to experience the high heights of happiness.
