"The idea, shared by many, that life is a vale of tears, is just as false as the idea shared by the great majority, the idea to which youth and health and riches incline you, that life is a place of entertainment. Life is a place of service, and in that service one has to suffer a great deal that is hard to bear, but more often to experience a great deal of joy. But that joy can be real only if people look upon their life as a service, and have a definite object in life outside themselves and their personal happiness."
