"No system can long command the loyalties of men and women which does not expect of them certain measures of discipline, and particularly self-discipline. The cost in comfort may be great. The sacrifice may be real. But this very demanding reality is the substance of which comes character and strength and nobility. Permissiveness never produced greatness. Integrity, loyalty, and strength are virtues whose sinews are developed through the struggles that go on within as we practice self-discipline under the demands of divinely spoken truth."
