Next, I read a theory by George R. R. Martin, a prolific writer of fantasy and science fiction. “I think there are two types of writers, the architects and the gardeners,” he explained. “The architects plan everything ahead of time . . . They have the whole thing designed and blueprinted out before they even nail the first board up. The gardeners dig a hole, drop in a seed . . . as the plant comes up and they water it, they don’t know how many branches it’s going to have, they find out as it grows.”
