The Richest Man in Babylon
This book is the basis of a lot of the "Wealth Building " statagies and courses you find through out the internet. I would highly recommend it to any one trying to improve thier life or even as a basis for teaching your children how to handle finances and build wealth.
Told in old times, the story is easy to follow and understand, but, the principles are made very clear through the story and at the end of each chapter.
One word of warning, once you read this you will probably never look at wealth the same again!
