Man's search for meaning

A recent discussion with the elder penguin (see here) about the meaning of life led me to reread Viktor Frankl's Man's Search for Meaning. In it, Frankl, psychotherapist and founder of the 3rd Viennese school of psychoanalysis or logotherapy (meaning therapy) discusses his personal experience surviving the horror of the Nazi concentration camps and how search for meaning is a guiding principle of human mental health. In this reading, I was struck by how logotherapy may be viewed as a forerunner of the more recent positive psychology movement of Seligman and others (see here). Chapter 3 of The Entrepreneurial Engineer touches on these issues by focusing on personal mission, values, goals, and vocation (see here).
