I cannot imagine a greater boon to a young man than to possess high ideals and purposes in life. Sometimes this high ideal is nothing more than strict performance of duty. Opportunity always comes to the one who performs the daily duties well. You will be called up higher if you perform the task set before you conscientiously, however may be the start. Only human beings with souls have ambition and inspirations.
Animals have no vision beyond existence.
Man only has ideals. Everything that exists in this world first pre-existed in the form of a vision, so first get a vision, an ideal, a purpose. It will lighten up your whole life. The second in the trilogy of life is energy, industry, work. This is the body.
