I led with my head for years. I loved to be up in my head, had no idea how to be anywhere else. But I never connected my constant neck pain (my daggone neck hurt until I was nikyu or ikkyu) to that problem. How interesting!
Like training (form, variation, no form), there is a time to be in the head to be mindful or the body, a time to see the conceptual and strategic process, and a time to just do it.
Lee would say that at first a punch is just a punch (you wing it). Then the punch becomes a science (you break it down and pay attention). In the end, a punch is just a punch (but this time its very different).
We also talk about the 4 levels of competence. The first is unconscious incompetence: it doesn't work, but you don't know it. Second is conscious incompetence: it doesn't work and you know it doesn't work. Third is conscious competence: it works when you pay attention. Fourth, it just works and you become aware of something else that needs you attention.
Thanks for taking the time to read and respond.
