We have no time to waste on insignificant books, hollow books, books that are there to please...We want books that cost their authors a great deal, books where you can feel the years of work, the backache, the writer's block, the author's panic at the thought that he might be lost: his discouragement, his courage, his anguish, his stubbornness, the risk of failure that he has taken.
