I cannot tell if this is in fact two authors incapable of writing beyond well worn cliches and dated references, or a deeply satirical comedic performance piece. I had to look up to see if these were written post 1962 (they were) to confirm that any of this could have qualified as acceptable writing, let alone guidance (they did not).
Please do literally anything other than get this book if you want any guidance on leadership. This book could not help one even aspiring to become a Deputy Manager at a GameSpot.
