Sun Tzu On The Art Of War [PDF ebook] 

First Published in 2005. This is the classic translation of the Chinese military masterpiece; it preserves the character and nuances of the Chinese original. The inspiration of Mao Tse Tung and countless generations of military leaders, it was written in antiquity and consists of thirteen chapters that reflect the mind of a born strategist and practical soldier whose maxims, full of acuteness and common sense, relate as much to the present day as they do to the military conditions of the time when they were written. As useful in the pursuit of success in modem business as it was in ancient warfare, this volume also relates to all aspects of personal and everyday life in which you must either be a winner or a loser.
