Reasoning back from the phenomena of form and thought, I come to one original thinking substance, and reasoning forward from this thinking substance, I come to a person’s power to cause the formation of the thing he thinks about. And by experiment, I find the reasoning true. This is my strongest proof. If one person who reads this book gets rich by doing what it tells him to do, that is evidence in support of my claim, but if every person who does what it tells him to do gets rich, that is positive proof until someone goes through the process and fails. The theory is true until the process fails, and this process will not fail, for everyone who does exactly what this book tells him to do will get rich.  

I have said that people get rich by doing things in a certain way, and in order to do so, people must become able to think in a certain way. A person’s way of doing things is the direct result of the way he thinks about things. To do things in the way you want to do them, you will have to acquire the ability to think the way you want to think. This is the first step toward getting rich. And to think what you want to think is to think TRUTH, regardless of appearances. Every individual has the natural and inherent power to think what he wants to think, but it requires far more effort to do so than it does to think the thoughts, which are suggested by appearances. To think according to appearances is easy; to think truth regardless of appearances is laborious and requires the expenditure of more power than any other work we are called upon to perform. There is no labour from which most people shrink as they do from that of sustained and consecutive thought. It is the hardest work in the world. This is especially true when truth is contrary to appearances.
