Here is where the work to creating your book really begins. Before you can start writing that book, you need to know what's going to happen in it - your story's beginning, middle and end.
So what is your story outline?
Well, it's generally the facts of your story and what happens throughout laid out in a plan. Your story outline allows you to plan - ahead of time - the story that you want to write. Try to make it as detailed as possible; know how it begins, what happens in the middle, what the climax is, and how you want it to end. I will provide a template form for you to use in this article.
And remember, these things take time, so don't rush through this because you're eager to start writing. If you don't know the story you want to tell and how you want to tell it, you'll get stuck before you finish.
I'll also say this: even if you plan your story, it is likely that you will still get stuck somewhere in the middle of your novel. Writer's block happens to everybody - even professionals. You just have to figure out what works best for you to overcome it. It could be freewriting, taking a break for a day or two and come back to it, watch or read something you find inspiring. There are many ways to overcome it, so don't let it get you down. Don't let it be the reason you quit.
