To have that sense of one's intrinsic worth which constitutes self-respect is potentially to have everything: the ability to discriminate, to love and to remain indifferent. To lack it is to be locked within oneself, paradoxically incapable of either love or indifference.
Without self-respect there can be no genuine success. Success won at the cost of self-respect is not success ? for what shall it profit a man if he gains the whole world and loses his own self-respect.
