" Where on earth did it come from? You can ask that question of any poem, and one inevitable answer is a simple one: work. No made thing springs up unbidden, even those that seem to. The poem that announced itself to the intoxicated Coleridge, before a knock at the door banished most of it from his memory, or the composition that sprung full blown into the head of Mozart, as he stepped down from a carriage after a satisfying dinner, seemed to pour from the artist's hand, so long schooled those hands had become. But years of labor inform those spontaneous productions. Though a poem over which one struggles may seem labored, it often prepares the way for new writing in which what's been learned emerges with an effortless grace. "
