The 33 Strategies of War - By Robert Greene (Remember: Strategy = Strategia = Art of War / Office of war chief !) And Psychology is a HUGE part of warfare!

From the link: http://en.wikipedia.org/wiki/The_33_Strategies_of_War

A "guide to the social game of everyday life informed by the  military principles in war." It is composed of discussions and examples on offensive and defensive strategies from a wide variety of people and conditions such as Napoleon Bonaparte, Lawrence of Arabia, Alexander the Great, and the Tet Offensive.

There are five parts: Self-Directed Warfare, Organizational (Team) Warfare, Defensive Warfare, Offensive Warfare and Unconventional (Dirty) Warfare. Each part contains a differing number of strategies.

STRATEGY ---> is a plan of action designed to achieve a vision. It derives from the Greek "στρατηγία" (Strategia) -> "Office of General, Command, Generalship".
