Carl Jung suggested that the first half of life was appropriately devoted to external accomplishments and the development of ego, while the second half should be devoted to the inward journey and letting go of ego. Although healthy ego functioning may precede confrontation with existential issues in healthy human development, it appears that the process is not necessarily chronologically sequential. Ego development may be satisfactorily completed in early childhood, and a call to inner development can be experienced at any age. It is no longer necessary to make a choice between devoting oneself exclusively to outer or inner development. On the contrary, it appears that optimum well-being demands both. Perhaps if the inner life were not so badly neglected in the educational system, there would be less need for remedial work in psychotherapy in order to redress the balance between inner and outer development.
When inner experience has been ignored or repressed throughout adolescence & early adulthood, it can become a source of considerable pain, anguish, & existential despair.
If, on the other hand, existential concerns can be acknowledged in conjunction with one's work in the world, one may discover inner resources for guidance, inspiration & deep satisfaction that transcend the boundaries of isolated individual existence."
