I am a huge fan of Sun Tzu's work titled "The Art of War". This is not a treatise on Stoicism, but it contains many life truths and wisdom also proclaimed by Stoics.
In fact, it was the first "philosophical" work I ever read, and it ultimately pushed me towards stoicism.
Have you read this book and do you have any thoughts about it?
Maybe you know other non-Stoic works that in some way inspired you to follow the path of stoicism? Please share your own experiences.
