The Middle is Where Story Happens
The middle is where you deliver on the story promise you made in the beginning. Part 1 addresses the need to expand your story, giving your reader more details about the character, expanding the problem, and leading to the Midpoint.
For the sake of clarity, I’ll use the four-act structure: beginning, before the midpoint, after the midpoint, and climax/resolution, so we all understand where we are in the story’s progress.
In Act 3, you switch directions. While the first part focused on expansion, this next section, after the midpoint, narrows the focus.
