This book was recommended to me as a self-help and management classic written 1,000 of years ago. To appreciate its value one must read it as a self-help and management book with a lot of attention to all the wisdom such ancient books carry.
I've re-read the book at different stages of my life and it gave me different insights. Its beauty is in its simplicity and I compare it to the reading of my favorite zen stories.
This is truly a classic with lots of meaning 'between the lines'.
Pick up a good translation so that this Asian wisdom does not get lost in the translation.
