Having been dated back to around 200 B.C., “The Art of War” is one of the oldest guides to military strategy that’s still around. Yet after all that time, the book has remained not only relevant but is probably still the most popular book around on strategy…it’s even been put into app version for smartphones.
To me that timelessness means that’s there’s more to “The Art of War” than it being merely a playbook for the battlefield. Many have taken its’ words and applied them to business, relationships, and life in-general. And all of these applications are valid. The heart of the text is the oft quoted “If you know the enemy and know yourself, your victory will not stand in doubt.”
If you’ve never gotten the chance to read it, or have but it’s been a while, I’d definitely recommend taking a look at: http://suntzusaid.com/ . They’ve got the full text in an easy to read format as well some downloadable ones if you want it offline. Read the whole thing or at least skim one of the 13 chapters with a title that catches your eye; you’re bound to stumble upon some wisdom to use in several aspect of your life.
