"What the young writer of today should contemplate is a dual profession, and incidentally, it would be the best thing in the world for his tortured creativeness to be forced to touch some nonliterary world, forced to remember what saner folk are daily up to. Let the young Balzac or Byron not only wear his elbows shiny at his desk, but let him with equal assiduity learn another and slightly more lucrative calling. But I would like him to keep out of advertising, journalism and the teaching of literature, if possible, because they are too much akin to writing. No let him become a doctor or a grocer, a mail-flying aviator, a farmer or a bacteriologist, a priest or a communist agitator, and the two professions together, he may make a living."
~~ SINCLAIR LEWIS, From The Writer, September 1936
