To construct a monster of a story, you need three things: Bones, flesh, and breath.
The bones are your outline. Who is your story about, what do they want, what is happening as a result, and how are they growing as a person — or monster?
Here's how to write your chapters when the bones are set:
A look inside my bones:
In the chapter I'm working on, my character gets word that his mentor is missing and presumably in danger. He has to leave the girl he’s been protecting behind to investigate.
Those are the bones of this chapter.
Dress them in flesh:
It’s time to think about the flesh that holds the bones together; The details, setting, character features, and how things work. Thinking is important.
Example: This scene is set at an off-the-grid compound for outcast clairvoyants. The character receives his message from a psychic medium. He is tall, dark, bald, covered in tattoos, and rocks a trench coat. The psychic has long red hair and looks like a kindergarten teacher. He suspects the spirit realm leader kidnapped his mentor for interrogation. He instructs the girl's family to tell her he is dead, despite how much pain it will cause her.
Describe the scene in as much detail as possible.
Breathe life into your creation:
Now, write your story.
Writing and thinking are separate in this system, which makes the act of writing much quicker. When already you know the details, it's easier to unleash the story from your mind.
Think before you write.
Save yourself some agony.
