If you feel irritated by the absurd remarks of two people whose conversation you happen to overhear, you should imagine that you are listening to a dialogue of two fools in a comedy.
Arthur SchopenhauerIn youth it is the outward aspect of things that most engages us; while in age, thought or reflection is the predominating qualityof the mind. Hence, youth is the time for poetry, and age is more inclined to philosophy. In practical affairs it is the same: a man shapes his resolutions in youth more by the impression that the outward world makes upon him; whereas, when he is old, it is thought that determines his actions.
Arthur SchopenhauerA man never is happy, but spends his whole life in striving after something which he thinks will make him so; he seldom attains his goal, and when he does, it is only to be disappointed; he is mostly shipwrecked in the end, and comes into harbor with mast and rigging gone. And then, it is all one whether he has been happy or miserable; for his life was never anything more than a present moment always vanishing; and now it is over.
