I would like you to know this humor.  Emmet Fox's copy right of this book was in 1931.  During the great depression a need of a book like this is apparent.  Positive thinking was needed to get us to summon our courage and innovate and solve problems.  Oh, yes.  The humor part is this.  There are many uses of the ideas in this book found in Hollywood's movies.  To name two: Poltergeist and Ghost give visual substance of the ideas making them better understood by me.  The scenes follow some of the book's most unusual concepts.  I laughed out loud when I had this realization.
