The Richest Man In Babylon
Over 4 million copies sold
George S Clason
I haven't become wealthy after reading this book, but my saving habits improved. It contains common-sense (but often forgotten) money management principles. The younger you read this book, the better it is. Furthermore, this classic of personal finance is short and easy to read.
Three notes from the book:
1- A part of all you earn is yours to keep. It should be not less than a tenth no matter how little you earn. It can be as much more as you can afford. Pay yourself first.
2- Opportunity is a haughty goddess who wastes no time with those who are unprepared.
3- That what each of us calls our "necessary expenses" will always grow to equal our incomes unless we protest to the contrary.
