Stuart: Centuries ago an anonymous English writer extended this advice:
“When you create or achieve something that is possibly one of your finest efforts, you will enjoy the admiration of your peers, but take care to ignore envious and cynical critics. Dealing with such critics can be compared to being nibbled to death by ducks.”
Also, there is Theodore Roosevelt's "The Man in the Arena" (a brilliant read)
(a couple of excerpts)
"It is not the critic who counts..."
"The credit belongs to the man who is actually in the arena..."
