Yes. Unfortunately the book is getting overly played out. Too much talk of it has our enemy aware. Personally I’m a fan of the 33 strategies. Prolly a favorite book of all time. I think it best to, instead of promoting specific books, promote the joy of reading and acquisition of knowledge—
Respectfully, great advice and good game is NEVER played out. For example the enemy can know we adopted a code. Doesn't matter if he knows, if we are on code we will win or at the very least hard as hell to defeat. The 48 laws is good game. Even if your boss sees it on your desk and he doesn't like you, its still going to be very hard for him to set you up if you are up on the game.
I'd also add:
Sun Tzu's 'Art of War'
The Richest Man in Babylon
Machiavelli's 'The Prince'
I'm not religious but Proverbs in the bible got good game.
