A Book of Five Rings: The Classic Guide to Strategy by Miyamoto Musashi

3.0

This book is apparently meant to be studied religiously.
If you just read it once, you probably won't get as much out of it.
There are points that were abstract enough to be applied in other contexts, but especially in the middle three books there is a lot of talk that is seemingly technical to swordfighting where it isn't as easy to distill the meaning for other domains. At the same time it is kept very vague, so the book won't really teach you that much by itself. Which is not surprising as it is heavily influenced by Zen.
I'll probably reread it some time, as it was fairly inspiring.
