"To set ourselves against men and fate is not a disposition of mind which is the noblest, and which does honour to us, nor is it that which is likely to procure us the greatest amount of tranquillity and cheerfulness. We ought rather to try to accommodate ourselves, so far as it is possible, to circumstances, to look on all that fate bestows upon us as a gift, being careful not to desire more, and least of all to be dissatisfied because all our desires are not gratified."
January 1, 1970
