Must it Be A Hero's Story?

I wonder about the popular reference to Joseph Campbell's hero's journey in the quest for self development or spiritual deepening.  There is a danger of it creating "the drama of me".

I understand the encouragement of the hero story; but I find, as one predisposed to sacrifice and heroics, that I want to move away from that imaging.  I'd rather just work on strengthening my courage.  I do not need to fancy myself noble for doing it.  I simply need to strengthen my courage and deepen my trust in the unknown.

If we are all heroes or heroines, then what is the need for them?  And if some are more heroic than others, does it not invite comparisons, leading to shame and blame?

I get it.  The journey is hard, and the metaphor of the hero's journey is intuitively wise and breathtaking.  But why place that journey in a category above others?  Why not say: this is the work we must do if we choose our own authenticity?  Not as heroes, but as lovers of soul's truth.
