The Richest Man in Babylon by George S. Clason is an aging chestnut. It's a classic in the field. Many later financial books are based on Clason's advice, which is framed in King James-style English rules:

Rule #1: Start Thy Purse Fattening — save 10% of everything you earn

Rule #2: Control Thy Expenditures — create a budget to live within your means

Rule #3: Make Thy Gold Multiply — invest the savings from rule one

Rule #4: Guard Thy Treasures From Loss — invest only where the principal is safe

Rule #5: Make of Thy Dwelling a Profitable Investment — own your home

Rule #6: Insure a Future Income — plan for retirement

Rule #7: Increase Thy Ability to Earn — become better educated, more skilled; respect yourself
