“Any criticism at all which depresses you to the extent that you feel you cannot ever write anything worth anything is from the Devil and to subject yourself to it is for you an occasion of sin. In you the talent is there and you are expected to use it. Whether the work itself is completely successful, or whether you ever get any worldly success out of it, is a matter of no concern to you. It is like the Japanese swordsmen who are indifferent to getting slain in the duel.”
