It was wonderful to walk down the long flights of stairs knowing that I’d had good luck working. I always worked until I had something done and I always stopped when I knew what was going to happen next. That way I could be sure of going on the next day. But sometimes when I was starting a new story and I could not get it going, I would sit in front of the fire and squeeze the peel of the little oranges into the edge of the flame and watch the sputter of blue that they made. I would stand and look out over the roofs of Paris and think, “Do not worry. You have always written before and you will write now. All you have to do is write one true sentence. Write the truest sentence that you know.” So finally I would write one true sentence, and then go on from there.
