In trouble to be troubled, Is to have your trouble doubled! [People who get upset and worried at the first sign of misfortune are only making their situation worse and thereby doubling their troubles. Stay calm and happy. Cool and joyful heads are more likely to survive and prevail.]
Daniel DefoeIt put me upon reflecting how little repining there would be among mankind at any condition of life, if people would rather compare their condition with those that were worse, in order to be thankful, than be always comparing them with those which are better, to assist their murmurings and complaining.
Daniel Defoe
