You were meant to achieve a great success. You can learn how to be well, strong, prosperous and happy. You can overcome disease, poverty, fear, worry, weakness of all kinds. You can do, have, and be far more than you ever dared to attempt, or even thought possible. You have wonderful powers of mind and body, that you need only recognize and use in order to reach the very height of your noblest ambitions and aspirations. The mission of these lessons is to help you believe all this, and prove it. The author of the lessons did prove it, before writing the lessons. They are not rainbow dreams of speculation, but live chapters of personal experience taken from the record of a teacher, healer and philosopher known throughout the world as one of the most powerful thinkers and leaders that the world has produced. Millions of people today who are using practical psychology in their professional duties, business problems, home relations or personal life gained their first knowledge of how to succeed from the author of these lessons. Not only a teacher, but a teacher of teachers, this pioneer metaphysician gave to hundreds of teachers and healers a vision of what they could do for their students and patients, and a vital impulse and force irresistible and inexhaustible.
