“Some people say it is morbid to be always thinking of one’s faults
“That would be all very well if most of us could stop thinking of them
“without soon beginning to think about those of other people.
“For, unfortunately, we enjoy thinking about other people’s faults.
“And in the proper sense of the word morbid,
“That is the most morbid pleasure in the world.
“We don’t like rationing which imposed upon us;
“But I suggest one form of rationing which we ought to impose on ourselves:
“Abstain from all thinking about other people’s faults, unless your duties as a teacher or a parent make it necessary to think about them
“Whenever the thoughts come unnecessarily into one’s mind, why not simply shove them away and think of one’s own faults instead?”
CS Lewis, The Search for God
