For the record, I never spent any time Character Building.
But I do now, when I come up with characters I write about. Some writers say that their characters just appear, fully formed, into their heads, like some weird cabbage-patch mythical offspring. Physically I guess that's true for me, that I can see what a character looks like sometimes right away. Otherwise I need to build my characters, put them together like Frankenstein in his lab (insert mad scientist laughter here). Okay, maybe not.
What does that mean? Well, when I do school visits, I explain it this way: If you were going to write a story about your best friend, you'd already know everything about them - what their parents are like, if they have any brothers and sisters (and how they get along), their favorite color, their favorite ice cream flavor, the fact that they are allergic to peanut butter, that their greatest ambition is to farm alpacas when they grow up. You'd remember that the scar on their chin is from when they fell out of your tree fort in second grade. You would know it all without having to work at it, and writing a story about your best friend would be easy.
I do the same thing. I get to know a character, make up all that stuff from nothing. I have a handy character worksheet that I use, that I got from another writer somewhere along the way, a fill-in-the blanks kind. It's dead useful. Some of the items I might never ever use in the story, but knowing them makes it easier to write the character in whatever situation I put them in, because I understand them, I've spent time with them, as it were, and learned all about them. If we went out to lunch, I know what we'd talk about.
Take for example, a character's bedroom. The story I write might never show the character's bedroom, but knowing what their bedroom looks like can be very useful, because a person's most personal space says something about them - whether they are messy or neat, for example. What color are the walls and why? Is the bed made or not? I might know what kinds of music they like (from the posters on the walls), do they have a desk and what is on it? What kinds of books are on their shelves- romances or horror novels (or reference books)?
This does NOT mean, however, that there are no surprises. Like best friends, characters (and everyone) have secrets, and you might discover something new about a character that you just hadn't considered. This recently happened to me- I was just sitting there, thinking about the book I'm working on, and something popped into my head about a secondary character, something important. I knew at once it was right and perfect, wondered why I hadn't realized it before. But I don't know if it will ever make it into the book. Or the next one. But I know, and that's enough.
I never used to do the character worksheets, used to learn about my characters as we went along. But for my last WIP (out on submission to agents and editors) I did write them, at least for the two main characters, and I found that I loved it. It made certain aspects of story writing so much easier, the story so much richer and deeper. I wondered why I'd never done it before. It's like cool, secret dossier like they have in spy stories, and you feel like some super secret spy, knowing everything about people you made up in your head! (okay, that sounds weird...)
Worksheets are much easier than hauling stones in a wheelbarrow or scrubbing pots. Given the choice, I'll take my version of character building over the summer camp version any day. Happy Writing!
