Musashi may have been emphasizing the need to cultivate one's ability to innovate, react, adapt.
Puts me to mind of an illustration my marketing 101 teacher told us once. A tool company was making 3/16" drill bits based on the assumption that what their customers wanted was 3/16"drill bits. They were product-based in their thinking. OTOH another company approached it from a different angle: what the customer wanted wasn't 3/16" drill bits but 3/16" holes. This company was solution-driven in their thinking. Ultimately, the solution-driven company prevailed in the marketplace.
I believe Musashi was a very solution-driven kind of guy.
