My Sensei strongly recommended this title soon after my joining his dojo. Upon finishing my initial reading, I'm glad he did. The title belies the breadth of application the wisdom and advice contained within; indeed, daily social life, work life, self acceptance, and death (no text even remotely related to Samurai/Bushido would be without the latter) can benefit from this book.
I found Kensho-san's book more accessible than the more traditional texts such as The Book of Five Rings. I suspect this is partly due to what's inevitably lost in translation of the original Japanese texts, though I believe the pragmatic treatment of these topics with a modern infusion plays a key role in this accessibility as well.
This is a book I shall refer to in the future, as it is of the sort that one can discover new insights from each rereading. I highly recommend it for anyone seeking a more fulfilling life.
