"Teaching, for the First Time in the History of the World, the True Philosophy upon which all Personal Success is Built."
Lesson XII, Concentration, teaches you how to focus your attention upon one subject at a time until you have worked out practical plans for mastering that subject. It will teach you how to ally yourself with others in such a manner that you may have the use of their entire knowledge to back you up in your own plans and purposes. It will give you a practical working knowledge of the forces around you, and show you how to harness and use these forces in furthering your own interests.
