The Art of War by Sun Tzu
The Art of War basically is old old book of Chinese advices how to fight, lead army and overcome enemy. I read two copies of it - one with only Sun Tzu`s thesis, second with other authors commentaries and explanations. Why I read it? Because I read one magazine article, where it was said, that Art of War was used by Cesar, Napoleon and others, as well as it is used in nowadays in USA army and some big companies trying to be the best in market.
Hmm, this book can really be used in company`s management, because some war strategies are quite similar to organization management. For example, need for clear and not doubtful commands, advice to put best soldiers (workers) on first line, importance of understanding ones own weaknesses and strengths etc.
Overall, it`s boring literature if one don`t think how to use those advices in life.
