An expert writer of stories needs to have some mastery of psychic distance—the distance the narrator stands from a character’s emotions, thoughts, and perceptions. No matter what viewpoint or person or verb tense you’re using for your story, your narration will sometimes go very close to character perception and sometimes stay quite distant.
There is a distinction between author, narrator, and character.
The author creates the story.
The narrator tells the story.
The character lives the story.
These are three distinct entities, which exist on different planes.
