"By and by people learn how not to believe, how not to trust, how to become chronic doubters. And this happens so slowly, in such small doses that you are never alert to what is happening to you. By the time it has happened, it is too late. This is what people call "experience". They call a person experienced if he has lost his contact with his heart: they say that he is a very experienced man, very clever, very cunning, nobody can deceive him."
