Well, think about your story's core idea. List the major conflicts and how they'll be resolved. Sketch out the character arcs and their growth. And don't forget to leave room for surprises and twists. That's how you can write a good novel outline.
First, you need to have a clear idea of the story's theme and genre. Then, break it down into chapters or sections. Outline the key events and character developments in each. Also, consider adding subplots to add depth and complexity.
Start by deciding on the main plot points and characters. Then, figure out the beginning, middle, and end. Make sure there's a logical flow and build up to a climax.
