From the story “The Teacher,” in Winesburg, Ohio. Yes, Sherwood Anderson. Yes.
The school teacher tried to bring home to the mind of the boy some conception of the difficulties he would have to face as a writer. “You will have to know life,” she declared, and her voice trembled with earnestness. She took hold of George Willard’s shoulders and turned him about so that she could look into his eyes. A passer-by might have thought them about to embrace. “If you are to become a writer you’ll have to stop fooling with words,” she explained. “It would be better to give up the notion of writing until you are better prepared. Now it’s time to be living. I don’t want to frighten you, but I would like to make you understand the import of what you think of attempting. You must not become a mere peddler of words. The thing to learn is to know what people are thinking about, not what they say.”
