This book is a foundational book for those who are interested in the modern self help, manifest your desires, movement.  Written about 1910, about a year before he died, Wallace Wattles sums up all he has learned about the methods of obtaining wealth. About the age of thirty, struggling to feed his family, Wallace seeks to find the answer of why some people are poor and others are not. The book shares his findings. This was the book that the DVD "The Secret" was based on.  The basic principles given by Wattles are very similar to present day prosperity writers.  The book is short and easy to read.  Other good books on the topic are "Law of Attraction" and "Ask and It is given" by Esther Hicks and "The Greatest Secret" (Internet book) by Darell Daybre
