Would just like to share something I learned of:
A political guide book, similar to Machiavel's The Prince, but a millenium older http://en.wikipedia.org/wiki/Arthashastra. I really like the schedule he proposes to the king's daily routine.
And Sun Bin (allegedly a descendent of Sun Tzu)'s art of war http://en.wikipedia.org/wiki/Sun_Bin%27s_Art_of_War
