Not Doctor Who. Just thought I’d make that clear.
The Who I’m talking about is your readers: the people who read your stories. Who is your target audience? What kind of people like your characters? Who do you think most needs the message in your story, and is your story directed towards them?
From my (limited) experience, I’ve learned that a lot of writers write what they themselves like to read. There are exceptions, but most people don’t write something they wouldn’t read themselves. As a teen writer, most of my work is YA. And as a girl, yes, most (but not all) of my main characters are girls. I’m sort-of adventurous, so I occassionally write something that doesn’t have a female main character, which is always interesting, for me, at least.
It’s important to know what your audience likes, and what turns them off. If you find that your book doesn’t fit your audience, that doesn’t necessarily mean that you should toss it out. Maybe you just need to find a different audience that does like your book. Look at other books that are like your book, and see who reads them. That could be your Who.
What about you? Do you write what you read? Who is your audience? Have you ever had trouble finding your audience?
