The Richest Man in Babylon by George S. Clason

Set in ancient Babylon, this book teaches timeless financial laws through parables of merchants, slaves, and kings. Lessons on saving, investing, debt, and discipline are woven into stories that make money management feel moral rather than mechanical.

Its enduring power lies in simplicity: pay yourself first, live below your means, and protect your wealth from foolish risk. Nearly a century later, its principles remain brutally relevant.
