In the wonderful world of novel creation there happen to be a number of pieces required to make the novel come together. As well as a healthy dose of plot, setting, and premise, the entire story almost always hinges upon the actions of the characters. Unfortunately for many budding authors, characters are not always the most cooperative beings in existence, as we all very well know. We're not mad, it's just those characters being the stubborn little bitches that they are! But for your sake, here is an article on how to get your characters and keep them in line.
Step one: Write a story! Sure, you might have characters wandering around in your head, but what good is keeping them in line if you don't have any reason to be controlling them and their urges. If they're just lounging around in the depths of your mind and drinking beer while you're doing absolutely nothing, there's no point in getting them to cooperate. They're just extensions of your imagination, as much as you may sometimes feel otherwise. Once you've gotten started on the story, that's where the real trouble begins, anyway. There's this thing called a plot and often times, the cast doesn't want to cooperate with the devious wiles of a world gone mad... at least, not the way you want them to.
So get writing. Whether or not you're an outliner, you're going to find that you require at least some notion of the direction of the plot, or your story will epically crash and burn. Generally once you're a few chapters in and the story's hinging on a critical moment, then you're going to find the problems begin. Joe doesn't want to fuck Cindy, because he's decided he's gay and damned if he's going anywhere near that women. And also, he crossdresses. And his father is trying to fuck Cindy as well, but since his father traveled forward in time he is younger and hotter than Joe.
Cindy isn't interested, and she's decided to take up a career in knitting, never mind that it's never going to support her and her illegitimate daughter. And that daughter of hers? She's a whore... who's trying to... take over... the universe? What? Really? And Deva was supposed to be evil!
Now that your story is in a nice, neat tangle, nowhere near the outline you'd initially created... now you need to get them back on track.
Step two: Find out the weaknesses of your characters. What makes them tick? Addictions? Love? Family? If you didn't start your story knowing these things, get busy. Make a list of all of the myriad of things you can use to get into their minds in revenge. If they're going to kick around in your head while trying to do things you really don't want them doing, you need blackmail, and that requires a decent amount of knowledge of the character you're trying to control.
