Written nearly a century ago and recently rediscovered by Rhonda Byrne, creator of The Secret
Becoming rich is not a matter of environment or talents. Money and property come to us as a result of doing things in a certain way. This is a natural law — the Law of Attraction — that specific actions always produce like effects. As a result, anyone who learns to do things in a certain way will ultimately become prosperous.
There exists a science of getting rich — and it is an exact science, like algebra or arithmetic and The Science of Getting Rich explains obtaining wealth in a practical, mathematical, manner. Wallace D. Wattles treats gaining riches as a simple equation, and if his simple, rational steps are done in a "certain way," the result will always equal wealth.
