Those who, in early life, learn to be courageous in the face of difficult tasks will be ready for the temptation that is apt to come to most young people to compromise with what they know to be right and true, to allow an exception "just this once!" in the straightforward course they have marked out for themselves. And the worst of it is that such a temptation is apt to come without the slightest warning and to present itself in such a light that it is easy to find an excuse for yielding, and to deem it quixotic and unreasonable not to yield. Once a young teacher who later became famous at Harvard, had occasion to censure a student who had given, as he believed, the wrong solution of a problem. On thinking the matter over at home, he found that the pupil was right and the teacher wrong. It was late at night and in the depth of winter, but he immediately started for the young man's room, at some distance from his own home, and asked for the man he had wronged. The delinquent, answering with some trepidation the untimely summons, found himself the recipient of a frank apology. "Why, in the name of reason, do you walk a mile in the rain for a perfectly unimportant thing?" this man was asked on another occasion. "Simply because I have discovered that it was a misstatement, and I could not sleep comfortably till I put it right," was the reply. Again the story is told of him that he borrowed a friend's horse to ride to a town where he expected to take the stage. He promised to leave the animal at a certain stable in the town. Upon reaching the place he found that the stage was several miles upon its way. This was a serious disappointment. A friend urged him to ride to the next town, where he could come up with the vehicle, promising himself to send after the borrowed horse and forward it to its owner. The temptation to accept the offer was great. The roads were ankle deep in mud, and the stage rapidly rolling on its way. The only obstacle was his promise to leave the horse at the appointed place. He declined the friendly offer, delivered the horse as he had promised, and, shouldering his baggage, set off on foot through the mud to catch the stage. At this time he was eighteen years old, but he had learned the lesson that made him remarkably efficient and dependable through life.
