There must be the keenest sense of duty, and with it must go the joy of living; there must be shame at the thought of shirking the hard work of the w… - Theodore Roosevelt

Let the man of learning, the man of lettered leisure, beware of that queer and cheap temptation to pose to himself and to others as a cynic, as the man who has outgrown emotions and beliefs, the man to whom good and evil are as one. The poorest way to face life is to face it with a sneer. There are many men who feel a kind of twisted pride in cynicism; there are many who confine themselves to criticism of the way others do what they themselves dare not even attempt. There is no more unhealthy being, no man less worthy of respect, than he who either really holds, or feigns to hold, an attitude of sneering disbelief toward all that is great and lofty, whether in achievement or in that noble effort which, even if it fails, comes to second achievement. A cynical habit of thought and speech, a readiness to criticize work which the critic himself never tries to perform, an intellectual aloofness which will not accept contact with life's realities — all these are marks, not as the possessor would fain to think, of superiority but of weakness. They mark the men unfit to bear their part painfully in the stern strife of living, who seek, in the affection of contempt for the achievements of others, to hide from others and from themselves in their own weakness. The role is easy; there is none easier, save only the role of the man who sneers alike at both criticism and performance.

A year later I was at a desolate little mud road ranch on the Deadwood trail. It was kept by a very capable and very forceful woman, with sound ideas of justice and abundantly well able to hold her own. Her husband was a worthless devil, who finally got drunk on some whisky he obtained from an outfit of Missouri bull-whackers — that is, freighters, driving ox wagons. Under the stimulus of the whisky he picked a quarrel with his wife and attempted to beat her. She knocked him down with a stove-lid lifter, and the admiring bull-whackers bore him off, leaving the lady in full possession of the ranch.

With self discipline most anything is possible.
