Francine Prose, in How to Read Like a Writer, quotes Isaac Babel on the painful responsibilities of writing:
I go over each sentence, time and again. I start by cutting all the words it can do without. You have to keep your eye on the job because words are very sly, the rubbishy ones go into hiding and you have to dig them out – repetitions, synonyms, things that simply don’t mean anything. … I go over every image, metaphor, comparison, to see if they are fresh and accurate. If you can’t find the right adjective for a noun, leave it alone. Let the noun stand by itself. A comparison must be as accurate as a slide rule, and as natural as the smell of fennel. … I take out all the participles and adverbs I can. … Adverbs are lighter. They can even lend you wings in a way. But too many of them make the language spineless. … A noun needs only one adjective, the choicest. Only a genius can afford two adjectives to one noun. … Line is as important in prose as in an engraving. It has to be clear and hard. … But the most important thing of all … is not to kill the story by working on it. Or else all your labor has been in vain. It’s like walking a tight-rope. Well, there it is. … We ought all to take an oath not to mess up our job.
