Knowledge comes, but wisdom lingers.
'Tis better to have loved and lost than never to have loved at all.
Ring out the false, ring in the true.
No man ever got very high by pulling other people down. The intelligent merchant does not knock his competitors. The sensible worker does not knock those who work with him. Don't knock your friends. Don't knock your enemies. Don't knock yourself.
The happiness of a man in this life does not consist in the absence but in the mastery of his passions.
