At some point in our lives, we all wanted to act like Musashi. To completely and relentlessly pursue an objective, to grow technically and spiritually. But as time goes by and opportunities change, we make small decisions that compound on a different lifestyle. Musashi is the archetype of effort and perseverance, but with a major difference: By choosing to live the samurai life, his decisions are always of life and death.

On a duel, Musashi tells about the way he uses the sword. There's no 50% or 80% strike. Not because he does not want to, but instead the swordsmanship does not allow. It doesn't matter what the samurai want, it's just the way of the sword.

The only bad part of the book are the extensive mentions of Japan geography. Characters go from mountain Khajiin to valley Sepukawa to walk the road Garafune, and there's a footnote saying how Garafune is the old name for Kogunake, north of Kyoto, east of Fukushima. I guess if you're familiar with Japan, you can understand all these references, but for everyone else, too much unknowns, and since they are so constant, sometimes you skip or consciously ignore a name.
