Found a good quote:
"Correct a fool and he will get angry with you. Correct a wise man and he will thank you."
Platitudes are for fools and wise men.
Rather than a quote it's Proverbs 9:8 rephrased.
What if a fool corrects you? What if the person correcting you isn't correct? The wise man laughs.
If the person correcting you, is not correct, then it is not a correction, and you have not been corrected.
Sorry. I love playing with words. Not really a paradox, but much the same sort of word play as in the famous.
The second sentence in this paragraph is true. The first sentence in this paragraph is false.
(If a fool corrects you, are they not a "wise fool".)
