“Well, I will tell you, and you must understand if you can. You belong to a singular race. Every man is a suffering-machine and a happiness- machine combined. The two functions work together harmoniously, with a fine and delicate precision, on the give-and-take principle. For every happiness turned out in the one department the other stands ready to modify it with a sorrow or a pain--maybe a dozen. In most cases the man's life is about equally divided between happiness and unhappiness. When this is not the case the unhappiness predominates--always; never the other. Sometimes a man's make and disposition are such that his misery- machine is able to do nearly all the business. Such a man goes through life almost ignorant of what happiness is. Everything he touches, everything he does, brings a misfortune upon him. You have seen such people? To that kind of a person life is not an advantage, is it? It is only a disaster. Sometimes for an hour's happiness a man's machinery makes him pay years of misery. Don't you know that? It happens every now and then.”
― Mark Twain, The Mysterious Stranger
