There's only really one story that any writer can tell with complete honesty, their own story.
Fiction authors that become successful have an ability to filter their story's telling in a way that allows others to learn from it. It's their story, dressed up in a way more people can relate to.
There's this thing called archetypes, and educated people will gladly point you to references of how they're currently understood. I'm not sure if my understanding matches one of the ones already out there. It's relatively common for me to share an understanding and have people tell me it is in resonance with something someone with a reputation has already written. In this case, I'm not aware of who understood archetypes in this way already, but maybe you've never read them either.
In a large part, these archetypes are identified as specific relational roles. The archetype of the 'mother', for example, is representative of the way we understand mothers to act toward their children. The archetypes are optional perspectives that we can choose to adopt in our interactions with others. They're a way for a society to communicate within itself, models of the various ways of conducting communication with other individuals.
A good fiction writer can take their story and tell it from the perspectives of the various archetypes. Storytelling is a language. It weaves the space between the seed and the blooming tree by describing how the two are bound by the glue of life over a span of time. Storytelling is the chronicle of the journey on the cycle of life. The truth that a writer learns on the journey, he is capable of binding and spinning into variant manifestations. A good fiction writer translates truth of his learning in a way that can help others recognize that truth in their own journey.
I am not a good fiction writer. I could be, now that I 'get it' though. Time, effort, and practice stand between me and there. I'd honestly rather not take that route. You can call it laziness, I'll call it the desire for efficiency.
Personally, my preference is to have an interesting enough journey that I can relate the truths directly to you as I figure them out. I'd like to be able to chronicle my story to you as it happens, but not always in a retelling of events. I'd like to be able to share with you 'what it looks like from here'. That's "my dream job".
This post you're reading is part of a story of a guy who saw the way things work and thought, "we can do better." This post you're reading is the 'true story' the film might be one day based upon. Can the protagonist just tell his story as it happens, or does he have to drape it in fiction to not starve to death?
