My characters have a tendency to perform similar actions with their hands, their eyes, or whatever other body part they happen to use a lot. They also have a tendency to possess one or two similar personality traits with characters from my other books. Usually it's so minor, I don't even realize I've written them that way. I've read the book three or four times, still not realizing the similarities. Then my editor gets a hold of it and kindly asks me if I intended to do that. My first thought is, "Of course!" until I stop for a moment to consider what she's pointed out. Sometimes I can still say, "Yes, I meant to do that." Other times I end up reviewing and revising because I honestly hadn't realized what I'd done.
It occurred to me that some of the traits I give my characters are my own. They are natural and I think nothing of them. For example, my characters use their hands a good deal. I wasn't aware of this, but in my last book, I ended up deleting more than fifty uses of the word "hand"! I've always thought that what a person does with their hands says a lot about them, but I had no idea how much of that ended up in my writing.
I certainly won't be removing these little traits from my characters' personalities, but I've learned that too much of a good thing is well . . . sometimes too much.
Is there something you find your characters tend to do a lot? Did you completely change the trait or find another way to covey that personality trait without overdoing?
