A lot of my procrastination in writing my story is coming from anxiety over making the finished product come from one "head." I have perspectives from a couple first persons, and some 3P Deep parts with no observer, that want to come together into this story.
I have been beating myself up over deciding "who is telling this part" to the point that the story is not getting down to paper.
I am at the point where I just want to get the story out, in the way that builds the intended arcs, and worry about the narrator after the fact.
For example,
Chap. 1
It wasn't the weather, or the age of the plane that would be bringing this story into our history books. No, It was nothing more complicated than a 5 millimeter grease fitting. It was clogged with dirt, so there would be no lubrication to one critical bearing. How ironic.
Chap. 2
I found myself drifting along the river, wet and cold, clinging to that log. What ever became of my good friend I may never know.
"Help!" I cried out with what little energy I had. It may not be enough. My mind raced over being lost and forgotten. Over never being found. Over my family never knowing where I am. Over never knowing why.
Chap. 3
"Officers, we have a witness over here. They said they were driving down 64 and saw a plane coming down. It was trailing black smoke."
The tall sheriff held up her hand to stay her partner, "How many were in the car?"
"There are two of them. Husband and wife, she saw it first and pointed it out while the husband was driving."
"Do me a favor and run their tag, would you?"
"Sheriff?"
"There may be more to this than meets the eye."
Just leaving this as is, it becomes the author's story, compiled by whatever resources (s)he had. I prefer wrapping a book into some singular in-world narrator however. In the example case, perhaps a forensic investigator was compiling a report and created the story from interviews, diaries, personal investigation, etc., which became the final compilation (I am certain there is writer's jargon for what I mean but I don't know it).
My question is about the difficulty of "wrapping" your story into an in-world narrator like this. To me, the story seems to flow out very naturally if I just hop around the different POVs as they fall into the plot; whereas taking Chap. 2 for example, and making it a diary entry acquired by the investigator/narrator could be done either in real-time or at the end as a "clean-up" step.
