First time writing from an idea
Question I have a couple ideas that I've envisioned an entire 90 minute movie about but can't figure out how to get the ideas into an enjoyable readable print form.
How do I get a fully thought out book idea into words for a novel?Answer:
Take one event or one scene at a time and describe it in words as best you can. Keep doing that until you reach the end of the story. Then go back and revise each section until the words are right and the story is what you want it to be.
Sadly, there are no shortcuts.
If your story is structured well (see the articles on this site for help with structure) that is half the battle. The other half is in your style of writing, and that cannot be taught, to a large extent. It must be developed through practice and exposure to the styles of other great storytellers via reading or actually copying out other stories. (Okay, there are a few guidelines, but no specific "how to" rules that apply universally.)
Just give yourself permission to write a bad first draft. Then focus on making the second draft better, same with the third draft, etc. until you know it's good.
