I read this book a very long time ago. It's a great tactical way to avoid battles.
If your enemy is stronger avoid
If your enemy is weaker show compassion
If you are evenly matched. Fight.
It applies to life as you point out.
Good post upvoted and resteemed.
It is amazing how principles from that book live on today.
Such simples rules but they have such a profound effect.
Thanks for reading @molometer
