Every character should want something, even if it is only a glass of water.
It's deceptively simple. This issue involves being sure that plot and character balance. Are you so interested in what a character does that you've lost focus on why. A writer's first impulse might be, "of course my character wants something! Isn't the big fight my next plot point? The biggest fight of his life! As he's concerned, it will be a fight to end all fights!"
Not so fast. Is it possible that this writer is so stoked for the fight that he (I imagine this writer's male, considering how interested he is in fistfights) may have forgotten how his character's want or desire leads up to that fight.
In the interest of clarity I'll bastardize Vonnegut's plain eloquence,
Every character should want something ... in order for his actions to make sense.
Action should follow desire. Desire should lead to action. Desire should also make sense.
Two Examples
I'll offer two king killers as examples Hamlet (killer of Claudius, King of Denmark) and Mario the Plumber (killer of Bowser, King of the Koopa).
- Hamlet makes sense. He's upset his uncle poured poison in his father's ear and unjustly became king. He wants revenge. He also wants to be sure revenge is the right action to take, so he thinks about it a lot. The play sets up Hamlet's dilemma, then based on that desire he acts.
- Mario makes less sense. He's upset because Bowser took Princess Peach and eventually kills him in order to free her. The game is superfun. But, like the majority of video games, superfun action outweighs clearly defined desire. Mario wants to save her, but his actions don't make sense. Why does he save her? Who's she to him that he ends up in the Koopa Kingdom slaughtering turtles and mushrooms out for strolls; eventually throwing an entire state into turmoil by assassinating its monarch? The game sets up Mario's dilemma (save the princess) and he acts, but his desire to do this does not make sense.

When the idea to write a story about an interesting happening was a work's prime mover. The plot may end up being great, but may also result in less well developed characters (cough, cough: Twilight).
Nonetheless: it's not hard to fix this by figuring out what a character wants. Since you know what a character does, ask yourself, what must this person want if they're going to do what they do?
An Exercise: Use Your Friends and Family
You're stuck. You have absolutely
no idea why a want would lead to an action. Tap people you know well.
A good fix I've found is just sitting down with a pen and paper and writing until I figure it out. I write out a summary of what happens and go from there. I write about people I know who might have done or are capable of doing something like this. Who do I know capable of such an action in the first place? What do I know about him or her that would make these actions sensible? What stories do I know about him or her that's similar to my story?
People you know well are great resources when you're trying to figure out the who's and why's of your characters.
Questions
- How do you use people you know as resources for fiction?
- What books or stories have you read with great plots and flimsy characters?
- How do you round out characters who seem flat?
- The classic question: plot first or character first?
Paulo Campos wrote his first novel in high school but didn't return to fiction until well into graduate school. He's since written three novels and a collection of short fiction. One of the novels and the collection seem good enough to shop for publication and are being revised. He was a recipient of Glimmer Train's "Best Start" competition in November 2009. His first published piece of short fiction will appear in the June 2010 issue of THEMA.
He lives in New York with his wife and two suspect cats.
