These books are about doing what you love, learning to laugh at yourself, becoming more prosperous, dealing with disaster, finding peace of mind, being able to forgive yourself and lots more. You will find out how happy people think, why rich people get richer, why all your bills come at once, how to understand yourself, and how to stop blaming your mother!
