"Not strategic at all"
This book has got nothing to do with "Strategy" as we perceive it in today's western world. You need to be a swords man to understand how Musashi refers to strategy: a posture and both action and reaction in a hand-to-hand combat using swords.
The book's description is highly misleading, probably due to literal translation.
Even the author wrote down that the majority of his techniques cannot be explained in detailed writing and basically have to be mastered by practice with the sword.
There are a few minor nuggets that elude to some Zen spirit, but they certainly don't warrant your time and money.
This book is unfortunately of no use to our current time (in any context for that matter), unless you plan on negotiating your next business deal using 'long swords' and 'winning' the deal, i.e. cut, slice, hack, or kill your opponent.
"Great book!"
I listened to this book while on a trip through the Caribbean and this a truly a great Hemmingway book. His style is crisp and clean, and yet, when you get into the story, has a profound and deep view on those simple and at the same time so complex details of life. With all those uncertainties and out-of-reach daily influences that we like to look away from in the 'developed' world. Great book and great flawless and good to listen to narration by Sutherland.
For Whom the Bell Tolls is a longer listen; however, another beautiful work by Hemmingway.
"Keen observations"
Yes, due to the numerous 'off script' remarks by the narrator/author.
Excellent and keen observations by the author.
