Frustration!
It’s just a few chapters. A bunch of chapters thrown together to make a story. You’ve got the idea, now just build it up and organize it! Chapters… They make the story.
If George Lucas, Phillip K. Dick, Isaac Asimov, William Gibson, Philip Palmer, and Vince Flynn can write a bunch of chapters and bind them together into a book, then so can you!
So why haven’t you?
They’re just chapters.
Chapters. Try to think of them as ficlys. Ficlys thrown together like a series.
Take your ideas and write a bunch of ficlys…or chapters…or whatever…and just write the damn book!
It’s just a story. Figure it out and tell the story!
