Life isn’t divided into genres. It’s a horrifying, romantic, tragic, comical, science-fiction cowboy detective novel. You know, with a bit of pornography if you're lucky.
If you want to write a fantasy story with Norse gods, sentient robots, and telepathic dinosaurs, you can do just that. Want to throw in a vampire and a lesbian unicorn while you're at it? Go ahead. Nothing's off limits. But the endless possibility of the genre is a trap. It's easy to get distracted by the glittering props available to you and forget what you're supposed to be doing: telling a good story. Don't get me wrong, magic is cool. But a nervous mother singing to her child at night while something moves quietly through the dark outside her house? That's a story. Handled properly, it's more dramatic than any apocalypse or goblin army could ever be.
Don't classify me, read me. I'm a writer, not a genre.
Sure, I knew the differences between a space opera and a hard-boiled detective story and a historical novel ... but I never cared about such differences. It seemed to me, then as now, that there are good stories and bad stories, and that was the only distinction that truly mattered.
George R.R. Martin
Good authors worry about genres great authors don't.
