Writing keeps me at my desk, constantly trying to write a perfect sentence. It is a great privilege to make one’s living from writing sentences. The sentence is the greatest invention of civilization. To sit all day long assembling these extraordinary strings of words is a marvelous thing… For me, a line has to sing before it does anything else. The great thrill is when a sentence that starts out being completely plain suddenly begins to sing, rising far above itself and above any expectation I might have had for it. That’s what keeps me going on those dark December days when I think about how I could be living instead of writing.
