The Prince is considered the all-time best book on political strategy. It has of late become a much-referred-to book for all competitive situations. Machiavelli's name is associated closely with his philosophy, as he well deserves. His other works are worth reading or hearing, as well, especially his Art of War and Belfagor: The Devil Who Took a Wife.
