"On a more technical level, a story takes a lot of words. And to generate words and phrases and images and so on, that will compel the reader to continue reading - that stand a chance of really grabbing a reader - the writer has to work out of a place of, let's say, familiarity and affection. The matrix of the story has to be made out of stuff the writer really knows about and likes. The writer can't be stretching and (purely) inventing all the time. Well, I can't, anyway."
