The Richest Man in Babylon
by George S. Clason
Our acts can be no wiser than our thoughts. Our thinking can be no wiser than our understanding.
Advice is one thing that is freely given away, but watch that you take only what is worth having.
You first learned to live upon less than you could earn. Next you learned to seek advice from those who were competent through their own experiences to give it. And, lastly, you have learned to make gold work for you.
