I guess one could see something from the concept in a phrase I first heard on the fishing schooner L.A. Dunton at Mystic Seaport. A phrase that humbled me because it took me a long time to understand its deeper meaning. The phrase. " Are you going to fish, or cut bait?" Meaning are you going to go fishing or are you just going to keep preparing to go, and never go.
However, the concept of 10 People 10 Colors [十人十色] also carries the idea of 10,000 people 10,000 colors [万人万色]. iow, everyone has different ideas, perceptions, ideas, taste, etc.
I often make an analogy between Tenkara and the game of GO. Tenkara and GO are both simple basic systems. And simple systems provide the most freedom of movement of where to go next or not go. The basic nature of both allows beginners to start playing right away, yet offers a depth of learning to keep your interest for a life time.
For me that is part of the beauty or appeal of Tenkara. From my POV, Tenkara is only as complicated as you want it to be. Or allow it to be. It’s your own choice whether to just fish by intuition or seek a deeper understanding of the many facets of Tenkara.
