Not everybody, however, has a genuine sense of humor. That calls for an altruistic detachment from oneself and a mysterious sympathy with others which is felt even before they open their mouths. Only the person who has also a gift for affection can have a true sense of humor.

Karl RahnerHow often I have found that we grow to maturity not by doing what we like, but by doing what we should. How true it is that not every 'should' is a compulsion, and not every 'like' is a high morality and true freedom.
