Differentiation alone is not enough for your personal brand
"A self that is only differentiated - not integrated - may attain great individual accomplishments, but risks being mired in self-centered egotism. By the same token, a person who self is based exclusively on integration will be well connected and secure, but lack autonomous individuality. Only when a person invests equal amounts of psychic energy in these two processes and avoids both selfishness and conformity is the self likely to relect complexity."
