I couldn’t find the thread for day 18 so thought I’d put this here. @Tony Marsh labeled the white belt and black belt being in the same location in his circle diagram. I can say this fits with martial arts, at least mine (hapkido). We have a saying that when you get your black belt to remember that you haven’t arrived, you are actually just beginning. You’ve gone around the circle back to the start point (white belt). Hapkido is big on circular movement. Now you know the fundamentals, but you are always refining them. Refining the fundamentals drives mastery. I just got my third degree and am about 4-5 years from my 4th. 4th degree is achieving the rank of hapkido master. Most of the techniques at the master level are actually white and yellow belt techniques but with added applications, but they are the same techniques. Makes sense, you’ve mastered the basics. Kind of what was explained in day 17 where you’re doing boxing practice back and forth defending a right jab over and over til you can’t miss. “I fear the man who’s practiced one kick 10,000 times”-Bruce Lee. It’s like answering “¿estás bien? Sí, estoy bien or no, no estoy bien” over and over until it becomes muscle memory. I guess that’s what resonates with me in this method is there is a martial arts type thinking to it. Hope this was helpful and if you’ve read this far and haven’t gotten the white to black belt course yet or are thinking about it, I’m pretty sure you can tell, I recommend it. Have a great day.
