"Cross out as many adjectives and adverbs as you can. ... It is comprehensible when I write: "The man sat on the grass," because it is clear and does not detain one's attention. On the other hand, it is difficult to figure out and hard on the brain if I write: "The tall, narrow-chested man of medium height and with a red beard sat down on the green grass that had already been trampled down by the pedestrians, sat down silently, looking around timidly and fearfully." The brain can't grasp all that at once, and art must be grasped at once, instantaneously."
