I’m reading Viktor Frankel’s Man’s Search For Meaning and came upon this great quote of Edith Weisskopf-Joelson:

Our current mental-hygiene philosophy stresses the idea that people ought to be happy, that unhappiness is a symptom of maladjustment. Such a value system might be responsible for the fact that the burden of unavoidable unhappiness is increased by unhappiness about being unhappy.
