It is necessary to handle yourself better when you have to cut down on food so you will not get too much hunger-thinking. Hunger is good discipline and you learn from it. And as long as they do not understand it you are ahead of them. Oh sure, I thought, I'm so far ahead of them now that I can't afford to eat regularly. It would not be bad if they caught up a little.
I knew I must write a novel. But it seemed an impossible thing to do when I had been trying with great difficulty to write paragraphs that would be the distillation of what made a novel. It was necessary to write longer stories now as you would train for a longer race. When I had written a novel before, the one that had been lost in the bag stolen at the Gare de Lyon, I still had the lyric facility of boyhood that was as perishable and deceptive as youth was. I knew it was probably a good thing that it was lost, but I knew too that I must write a novel. I would put it off though until I could not help doing it. I was damned if I would write one because it was what I should do if we were to eat regularly. When I had to write it, then it would be the only thing to do and there would be no choice. Let the pressure build. In the meantime I would write a long story about whatever I knew best.
~ Ernest Hemingway, A Moveable Feast
