"How often, for example, a young man desires affection from someone who cannot give it to him, who has it not to give! From such a desire as that comes often a great deal of sadness, jealousy and much other ill-feeling. You will say that such a desire is natural; undoubtedly it is, and affection which is returned is a great source of happiness. Yet if it cannot be returned, a man should have the strength to accept the situation, and not allow sorrow to be caused by the unsatisfied desire."
