One should never be discouraged or disappointed in life. Man has the key of his own life in his hand, if he only knew it. It is absurd to say, "I have not got that quality"; there is no quality in the world that man has not got, either good or bad; and the soundest psychology is to say to oneself that one has the quality one thinks most desirable, most attractive; and not that quality which one does not think desirable.
