Arthur Schopenhauer: “Talent hits a target no one else can hit. Genius hits a target no one else can see.”

“I suppose flattery hurts no one, that is, if he doesn’t inhale.” — Adlai Stevenson

And like ConnectingDots, I have a mantra that helps me though many a moment: "Never attribute to malice that which can be adequately explained by stupidity." It's amazing how many problems disappear when people (including me) stop assuming it's all about them, and therefore the other guy did it on purpose.
