They will impose a rigorous set of standards upon themselves in order to try to measure up to that image. They will cultivate pride, and with that will come the vulnerabilities associated with pride that lacks any foundation. Finally, they will despise themselves for all their limitations. Vicious circles will operate to strengthen all of these effects. Eventually, as they grow to adulthood, a particular "solution" to all the inner conflicts and vulnerabilities will solidify. They will be either 

expansive, displaying symptoms of narcissism, perfectionism, or vindictiveness
self-effacing and compulsively compliant, displaying symptoms of neediness or codependence
resigned, displaying schizoid tendenciesIn Horneys view, mild anxiety disorders and full-blown personality disorders all fall under her basic scheme of neurosis as variations in the degree of severity and in the individual dynamics. The opposite of neurosis is a condition Horney calls self-realization, a state of being in which the person responds to the world with the full depth of their spontaneous feelings, rather than with anxiety-driven compulsion. Thus the person grows to actualize their inborn potentialities. Horney compares this process to an acorn that grows and becomes a tree: the acorn has had the potential for a tree inside it all along.

Carl Jung found his approach particularly effective for patients who are well adjusted by social standards but are troubled by existential questions. Jung claims to have "frequently seen people become neurotic when they content themselves with inadequate or wrong answers to the questions of life". : 140  Accordingly, the majority of his patients "consisted not of believers but of those who had lost their faith". : 140  A contemporary person, according to Jung, …is blind to the fact that, with all his rationality and efficiency, he is possessed by powers that are beyond his control. His gods and demons have not disappeared at all; they have merely got new names.
