Here is a part of the first chapter of "The Science of Getting Rich" book.
WHATEVER may be said in praise of poverty, the fact remains that it is not possible to live a really complete or successful life unless one is rich. No man can rise to his greatest possible height in talent or soul development unless he has plenty of money; for to unfold the soul and to develop talent he must have many things to use, and he cannot have these things unless he has money to buy them with.
A man develops in mind, soul, and body by making use of things, and society is so organized that man must have money in order to become the possessor of things; therefore, the basis of all advancement for man must be the Science of getting rich.
The object of all life is development; and everything that lives has an inalienable right to all the development it is capable of attaining.
Man's right to life means his right to have the free and unrestricted use of all the things which may be necessary to his fullest mental, spiritual, and physical unfoldment; or, in other words, his right to be rich.
In this book, I shall not speak of riches in a figurative way; to be really rich does not mean to be satisfied or contented with a little. No man ought to be satisfied with a little if he is capable of using and enjoying more. The purpose of Nature is the advancement and unfoldment of life; and every man should have all that can contribute to the power; elegance, beauty, and richness of life; to be content with less is sinful.
It is perfectly right that you should desire to be rich; if you are a normal man or woman you cannot help doing so. It is perfectly right that you should give your best attention to the Science of Getting Rich, for it is the noblest and most necessary of all studies. If you neglect this study, you are derelict in your duty to yourself, to God and humanity; for you can render to God and humanity no greater service than to make the most of yourself.
