I think the Deason quote "If you're not big enough to stand criticism, you're too small to be praised" hits home the most for me. Nobody likes a "braggart," and nobody likes a "know-it-all--" both of which, I am certain I have been guilty of, many a time, including on steemit, no less! Anyway, It's absurd for anyone to think they are "perfect." And someone who can't accept when they're wrong is quite an intolerable character.
