Wallace D. Wattles 
The Science of Getting Rich 

‚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.‘–So begins ‚The Science of Getting Rich‘, Wallace D. Wattle’s classic treatise on achieving financial success through the power of positive thinking.
