I have always been fascinated by the public interest in the book The Art of War by Sun Tzu. I have seen it gestured to as a source of wisdom and philosophy by everyone from business gurus, influencers, and even some politicians. In our culture, we think of The Art of War as containing great and practical advice that we can apply in our own lives.
But then you go and read it (which I recommend, it’s available for free online and is only 6,000 words), and you find that it really is just the basics of ancient warfare.
