Carl Jung broke away from Sigmund Freud due to differing views on concepts like the libido, the structure of the psyche, and the nature of the unconscious. Jung believed that the unconscious contained more than just repressed desires, and included a "collective unconscious" containing archetypes inherited by all humans. A key part of Jung's theory was the concept of individuation - the process of integrating one's conscious and unconscious elements to achieve wholeness. This involved acknowledging archetypes like anima/animus and the shadow. Jung saw individuation occurring over three stages from birth to death.
