Have you ever come across an interview where a fantasy author explains that their Chosen One/prodigy hero's journey is a metaphor for how ordinary people can change the world?
This is bullshit. Most people do not have extraordinary levels of talent or intellect. Most people don't have magic powers. Most people don't have a team of other heroes encouraging and nurturing them along their journey.
If you want to show that an ordinary person can change the world, write about an ordinary person.
