Which book to read next? (After Athol Kay's book.)

I read "The Mindful Attraction Plan" by Athol Kay. It's decent, but not my favorite.

I recently purchased "When I Say No I Feel Guilty", "The Rational Male", " Meditations", "48 Laws of Power", " The 33 Strategies of War", "Mastery", and "No More Mr. Nice Guy".

Any suggestions on which one I should read next?
