Over on Letters of Note: Even prolific Tarzan creator Edgar Rice Burroughs (1875–1950) had some down moments. As he writes to his daughter in January 1941: "If anyone says a kind word about my work nowadays, as you did, I nearly break down and cry. I have had so many refusals lately and had my classics so gratuitously insulted over here that I have lost confidence in myself."
