“ Why is it that people who are absorbed by something are seen as sad? I can't explain it, but for me it reverses the true state of affairs. To be engaged is to be a part, to be absorbed and fulfilled. To be cool, to be detached from things and to have no passionate feelings is the real sadness. At the heart of depression, that quintessentially modern malaise, is a deep sense of separation from the rest of life. ”
