In dealing with fools you must adopt the following philosophy: they are simply a part of life, like rocks or furniture. All of us have foolish sides, moments in which we lose our heads and think more of our ego or short-term goals. It is human nature. Seeing this foolishness within you, you can then accept it in others. This will allow you to smile at their antics, to tolerate their presence as you would a silly child, and to avoid the madness of trying to change them. It is all part of the human comedy, and it is nothing to get upset about or lose sleep over.
