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 DefoeAll the good things of the world are no further good to us than as they are of use; and of all we may heap up we enjoy only as much as we can use, and no more.
Daniel DefoeI could not forbear getting up to the top of a little mountain, and looking out to sea, in hopes of seeing a ship : then fancy that, at a vast distance, I spied a sail, please myself with the hopes of it, and, after looking steadily, till I was almost blind, lose it quite, and sit down and weep like a child, and thus increase my misery by my folly.
Daniel Defoe
