Give yourself to something great, enroll under the banner of a high cause, choose as your own some standard of self-sacrifice, attach yourself to a movement that makes not for your own gain but for the welfare of men, and you will have come upon a richly satisfying as well as engrossing adventure. Either your spirit will greatly and bravely, nobly and self-forgettingly adventure, or you will be in danger of yielding to the dominance of your appetites, you will be in peril of being overcome by your masterful passions. Dare to give every power of your life to the furtherance of a mighty cause. Let your spirit come under the dominance of a high and exalting enthusiasm. So will you gain the mastery over yourself, not as a matter of prudence, not as a matter of caution, not as a matter of timidity, not as a matter of duty. Let something so high and noble come into your life that it shall be expulsive of everything low and mean. The men one honors most, the men one has reason to cherish most highly, are those into whose lives something so lofty and commanding has come as to have left no room for the mean and petty. Having given themselves to the furtherance of a high and exalted ideal, life leaves no place for the mean. The selfish and the unworthy retreats with the precipitancy of the coward before the imperiousness of the noble impulse, the divine aim. And to their honor be it said, young men and women will rise to the highest level when it invites or challenges. There is in the heart of youth a limitless capacity for ardent devotion to causes of nobleness if but it be evoked and guided. And youth, too, understands how noble the venturesome deed may be even when utterly futile, how sublime in essence even when broken and foredoomed.
