Query: Don't waste your money

I was recommended this book by an acquaintance who claimed that this book changed his life. Curious as to what all the fuss was about, I bought a copy and read it. This book is the most over-rated garbage I have ever had the misfortune to waste good money on. The "fable" is banal and shallow and I cannot for the life of me figure out why anyone would consider reading this trash a life changing endeavour. Don't do as I did and waste your money on this book!
