Ten men have failed from defect in morals, where one has failed from defect in intellect. - Horace Mann

He who cannot resist temptation is not a man. He is wanting in the highest attributes of humanity.

Whether a young man shall reap pleasure or pain from winning the objects of his choice, depends, not only upon his wisdom or folly in selecting those objects, but upon the right or wrong methods by which he pursues them. Hence, a knowledge what to select and how to pursue, is as necessary to the highest happiness as virtue herself. Virtue is an angel, but she is a blind one, and must ask of Knowledge to show her the pathway that leads to her goal.

Be sure of the fact, before you lose time in searching for a cause.
