As Napoleon Hill Quotes: "Anything that robs you of peace of mind robs you of life's greatest wealth. You may lose peace of mind by pursuing money too anxiously or by trying to acquire more money that you can spend wisely. Money you earn through constructive work is the money most likely to benefit you. It is a mistake to deprive young people of the need to know life through work. Anyone can save, and the effort you make towards saving a percentage of your income gives you a true knowledge of the value of money. Saving also prepares you to handle many opportunities which otherwise might slip by."
