Make this purpose his supreme duty, and should devote himself to its attainment, not allowing his thoughts to wander away into ephemeral fancies, longings, and imaginings. This is the royal road to self-control and true concentration of thought.
A man should conceive of a legitimate purpose in his heart, and set out to accomplish it. He should make this purpose the centralizing point of his thoughts.
They who have no central purpose in their life fall an easy prey to petty worries, fears, troubles, and self-pityings, all of which are indications of weakness.
