Psychic birth occurs at puberty when the psyche assumes a definite content. Preparatory activities mark the time from adolescence through young adulthood. In the period of middle age when success has been achieved the personality undergoes changes. Psychic energy must be rechanneled into the inner world of the unconscious and the attitude must shift from extraversion to introversion. Individuation (the realization of one’s capabilities) can occur only in middle age when people must confront the unconscious and abandon the behaviors and values that guided the first half of life. Transcendence involves the unification of the personality.
