Little Dorrit by Charles Dickens

To be in the halting state of Mr Henry Gowan; to have left one of two powers in disgust; to want the necessary qualifications for finding promotion with another, and to be loitering moodily about on neutral ground, cursing both; is to be in a situation unwholesome for the mind, which time is not likely to improve. The worst class of sum worked in the every-day world is cyphered by the diseased arithmeticians who are always in the rule of Subtraction as to the merits and successes of others, and never in Addition as to their own.

The habit, too, of seeking some sort of recompense in the discontented boast of being disappointed, is a habit fraught with degeneracy. A certain idle carelessness and recklessness of consistency soon comes of it. To bring deserving things down by setting undeserving things up is one of its perverted delights; and there is no playing fast and loose with the truth, in any game, without growing the worse for it.
