Arthur Schopenhauer

“A man is never happy, but spends his whole life in striving after something that 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 harbour with mast and rigging gone. And then, it is all one whether he is happy or miserable; for his life was never anything more than a present moment always vanishing; and now it is over.”

— Arthur Schopenhauer
