Truth.
And I look forward to reading your story -- or novella -- for 500K word novel - or whatever this story eventually turns into --when you finish it.
Tag me when you do, okay?
That being said, I'm a writing coach and editor and one of the most useful things I do for the medium writers I work with is help them turn the 8 minute drafts they bring to me into the 4 minute stories they're meant to be.
Just about everything published on Medium needs to be focused and trimmed.
But I'm guessing that as a pub editor, you already know this.
