Let's take it from the top! NaNo doesn't start until November 1, which means that we have a couple weeks to prepare. Shall we take advantage of that?
In NaNoWriMo, you must start your book on the 1st day. That means that you can't continue a book that you've been writing before November 1. However, you are greatly encouraged to use outlines!
I highly, highly,
highly suggest outlines! Of course, there are some writers who don't need them, but I think that only people who have tried the outline thing and it didn't work should claim they don't need one. I thought I didn't need one. But last NaNo, I knew that I wouldn't be able to remember all of my awesome plot, so I wrote it down in an outline.
Before, I had problems with continuing books. After the first chapter (or page, or paragraph) I would lose track of the path. It seemed like I could never get through. But when I had an outline, that changed.
With an outline, I actually have a sense of direction. It lets me know that I can't spend forever on this one scene because something else needs to get done after it. If your greatest problem (or one of them) in writing is stalling, like me, then you might want to try an outline.
But where do you start?
I suggest starting with the simple, bare bones. I'll just make up a simple, kind of silly story that I can show you as an example.
Okay: point A. The introduction. This will contain stuff like the character's name, the current situation, just basic stuff you and your reader will need to know.
Point B: The rising situation. This is the point where the problem is realized and things begin to look like trouble.
Point C: The climax. Everything comes to a boiling point.
Point D: The wind-down. The problem is solved (unless your story is a tragedy, that is), we see whether or not the character makes it through, and we see what happens afterward.
Now here's the example:
A: Introduction
1. Maximilian James III lives in France.
2. A collector who rescues animals.
3. Has dogs, cats, parrots, monkeys, and the occasional elephant.
4. Max is very rich.
B: Rising Situation
1. Maximilian finds a kitten in Paris.
2. Kitten has a small message around its collar.
3. Max finds out he's intercepted a secret code.
4. The code is a communication between two infamous spies.
5. Josephina and Katharina D'Eli, twin spies, are angry at him.
6. They need to get the code back.
C: Climax
1. Josephina and Katharina begin spying on Max.
2. They find out where he lives.
3. When Max is away, they break into his house.
4. They find the kitten, which still has the code on its collar.
5. One of the monkey quietly sets loose a parrot to tell Max.
5. Josephina and Katharina begin to sneak away.
D: Wind-Down
1. The parrot finds Max, who is walking back to the house.
2. It tells him about the spies.
3. Just as Josephina and Katharina leave, the police and Max show up.
4. Max arrests them and reclaims the kitten.
5. The police use the code to intercept many secret messages from the spy ring Josephina and Katharina were involved in.
6. The police break up the spy ring, Max has the kitten, and they all live happily ever after.
(this story is mine. I claim the right of property laid out in law and in the Bible. Do not copy)As you can see, it's pretty general, but it works for me.
Also, this is just the outline I use. There are many other kinds, but I like this one. It's enough to keep me writing. =)
After I've outlined the skeleton of the story, I like to go back and flesh out some in the outline. However, don't get in to too much detail, unless you have a brilliant idea for detail that you think you won't be able to remember until November. Outlines can get from just a quarter of a page to nearly a novel in itself.
Even if you think you're a non-outline writer (also known as seat-of-the-pants writer), I suggest just giving it a try if you never have. If it doesn't work, then you can just ditch the outline. If it does, then you might have never known if you hadn't tried it.
