Apologies if this annoyingly dull, but I'm rereading Dale Carnegie's How To Win Friends and Influence People (forming a cult is all, let me know if interested) and came across a line I've heard in simpler terms. "Any fool can criticize, condemn and complain- and most fools do. But it takes character and self-control to be understanding and forgiving." I shouldn't need to draw lines between this quote and the lyric I think it may have been turned into. The truth of the idea is simple, so it wouldn't be shocking if Carnegie and Morrissey both thought of it independently.
