“The narcissist and the megalomaniac believe that happiness is possible, though they may adopt mistaken means of achieving it; but the man who seeks intoxication, in whatever form, has given up hope except in oblivion. In his case, the first thing to be done is to persuade him that happiness is desirable. Men who are unhappy, like men who sleep badly, are always proud of the fact.
Perhaps their pride is like that of the fox who had lost his tail; if so, the way to cure it is to point out to them how they can grow a new tail. Very few men, I believe, will deliberately choose unhappiness if they see a way of being happy.”
