According to psychologist Carl Jung, there are divisions into one's mind. The "Self" (often described as "Higher-Self" or "Soul") is what hold all of those divisions together (or try to). It is what gives balance and stability of who you truly are or can be.
The hero archetype is the personification of the ego (I won't explain it here, it would be a huge explanation.). In Campbell's and Vogler's writings, there are mentions about the "Shadow" as well. It is portrayed as an antagonist to the hero, but not necessarily the villain.
This "ego-driven" journey is about proving something to the world. The Hero has something that is not well acepted in his society and he has to left in order to mature himself for then he can return renewed and stronger. They often want save the world aganist what he (or his society) considered to be evil, but there are other people on the other side that have their own heroes. So we got ourselves a bunch of blue and red heroes fighting aganist each other.
There isn't, a specific journey for the Self, which is the central part of the human's psyche. We tend to forget it in our polarized society as we need it more than ever.
