Image Nations has reviewed a book that was useful to me when I first entered the corporate world. It was (and still is) a dog-eat-dog world I wasn't ready for but quickly got in the mix for the high worldly returns, and the thrill of clawing a top spot.
I learnt a lot from Sun Tzu's The Art of War that helped me deal with the harsh and highly competitive work environment. I have no doubt that anyone that reads it will pickup at least one tip to a better life.
Patience in battle - any type of battle, is what The Art of War helped me develop that I still use.
Take a look at Nana's outstanding review of this book.
