In all provinces of life, it is unhappily the case, that whatever is to be accomplished by a number of co-operating men and circumstances cannot long continue perfect. Of an acting company as well as of a kingdom, of a circle of friends as well as of an army, you may commonly select the moment when it may be said that all was standing on the highest pinnacle of harmony, perfection, contentment, and activity. But alterations will ere long occur; the individuals that compose the body often change; new members are added; the persons are no longer suited to the circumstances, or the circumstances to the persons; what was formerly united quickly falls asunder.

Johann Wolfgang von Goethe
