Sometimes, looking at the many books I have at home, I feel I shall die before I come to the end of them, yet I cannot resist the temptation of buying new books. Whenever I walk into a bookstore and find a book on one of my hobbies - for example, Old English or Old Norse poetry - I say to myself, "What a pity I can't buy that book, for I already have a copy at home.

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.
