Hi Leo,
I suspect it would be a great service if you were to help educate the public about the Jungian model of the psyche. You have discussed at length the concept of ego, and this is quite significant. However, specific focus on the concept of shadow is an important aspect of ego for those pursuing personal development; this includes a description of what the shadow is, what (may) comprise it, strategies for bringing this information into the light of consciousness and using it to better understand ourselves and to aid in the process of self-actualization, and the ways in which human beings cope with shadow material, including denial/repression, projection (which, as I understand, you have already covered), integration, and transmutation.
I appreciate your time,
Hailey
