Jung noted that in the first half of life we must focus on the objective world of reality-education, career, and family. In contrast, the second half of life must be devoted to the inner, subjective world that hereto fore had been neglected. The attitude of the personality must shift from extraversion to introversion. The focus on consciousness must be tempered by an awareness of the unconscious. Our interests must shift from the physical and material to the spiritual, philosophical, and intuitive. A balance among all facets of the personality must replace the previous one-sidedness of the personality (That is, the focus on consciousness)
Thus, at middle age we must begin the process of realizing or actualizing the self. If we are successful in integrating the unconscious with the conscious, we are in a position to attain a new level of positive psychological health, a condition Jung called individuation.
