When I first heard of the Hero with A Thousand Faces, it was when I was researching the “Hero’s Journey” framework for writing stories. If you look it up, you can definitely see some informational summaries in articles and YouTube videos.
But when I finally picked up the book and read it myself. The book does not primarily offer a guideline for story-writing. Instead, it is a deep dive into the folklore of different cultures of mankind, leading to the wondering of the existence “collective consciousness”; how many culture’s legends seem to follow a similar journey of personal growth, despite different characters and different settings.
