The comment that stung also made the next version better. Critics are free editors with bad manners.

Useful criticism and kind criticism are different things, and they arrive separately more often than not. Somebody said it badly, possibly enjoyed saying it, and was still pointing at something real, which leaves you to sort the accuracy from the delivery. That sorting is unpleasant work, and it is where most of the value sits.

When something stings, wait a day and then read it again for content only. Take whatever would improve the next attempt and discard the tone entirely. You owe the critic nothing, including agreement, and you can still keep the part that was true.
