A swordsman, undefeated.
A painter, on the side.
A teacher, at the end.
Musashi was born into a small samurai family in late-sixteenth-century Japan. He fought his first duel at thirteen, his sixtieth-something before he turned thirty, and walked away from each one alive while his opponent did not. He also painted. He carved Buddhist statues. He wrote calligraphy. He retired to a cave on Mount Iwato and spent his last weeks composing the book that has anchored every serious craftsman who has found it since.
We are not selling katanas. We are selling a way. The way is the same in any discipline that takes a long time to learn: master the small unit, repeat the small unit until it does not cost you, and only then begin to compose. The katana is rented. The framework is rented. The hand that holds either is the part that compounds.
