The document discusses the concept of the "hero's journey" storyline that is found across many cultures and stories. Joseph Campbell's research identified common stages in this narrative structure, including the hero's birth and humble origins, a period of exile and learning survival skills in childhood, and a series of trials faced by the hero once they accept a call to adventure. Popular books that follow this hero journey pattern, like Harry Potter and The Chronicles of Narnia, were among the most beloved by Australian children in a recent survey.
