Query: A Great Classic

This is a classic of self-help books. And Dale Carnegie is a pioneer in this field. He's the one alot of the modern day authors first learned from.The book gives you alot of good basic advice on how to stop worrying. It is also filled with examples of people's lives.The examples are really old, because the book was written in the 1940s, but they are still true today.
