This book is a classic. I realized today I've never recommended it to you, so today I will right that wrong.
Before it was a book, it was a speech - a speech that was given more than 6,000 times. The writer and presenter Russell Conwell was a Baptist minister, lawyer and writer. He was also the founder and first President of Temple University - a university that was largely founded from the proceeds of him giving this speech.
The book tells a story, that I will not tell you much about. Since it's a short story, and a story well past it's copyright, you can easily find copies at little or no cost online (you also can find copies at Amazon).
Suffice it to say that this story engages you and helps you learn a very empowering and important truth.
While this book is valuable to anyone at any age -- I encourage you to have your children and co-workers read it. Its message may be especially important now as we live through what some call a Recession (though I don't believe in such a thing - and here's why).
Bottom line, everyone should read this book. It's not long; it's an important piece of American literature; and its message, when taken to heart and put into action, can change your life.
You can pick up a copy at Amazon or your favorite book seller.
