This book is total nonsense and is an interpretation of an interpretation of an interpretation. It glosses over highly complex theories and ignores other very valuable aspects of Adlerian psychology. These best seller simplified psychology books with a catchy title are dangerous, as they close minds towards complex issues rather than open them. It gives ignorant people yet another tool with which to pre judge others. It also mainly lines the pockets of the authors... until the next fad takes over. Read the original theories if you are interested, make up your own mind on the whole, not this filtered one sided nonsense ....
