The Richest Man in Babylon by George S. Clason

The main take away is save 10% of your earnings for later, 20% of your earnings should go to paying down debt, and the remaining 70% of your earnings are to be your living expenses. Sound advice and it is advice given in several other financial literacy books. The 10% saved, is really at least 10% saved and invest it into wise investments that are researched and will have some form of interest. How the reader decides to save and invest the 10% of their earnings is really up to them, but advice is given on how to tell a wise investment from a foolish one. 20% of earnings to pay down debt, is debt that is already there. Most financial planners will tell  you that just paying the minimum is not going to help, so 20% of earnings to pay down debt does make sense. 70% of earnings to live on, also makes sense. If you figure mortgage, utilities, other loans that need to be paid, and other bills go there, plus the 20% to pay extra on these debts is doable. How you use the extra 20% depends on what other financial planners you listen to and what methods you want to use.
