My mentor is out of town for the week, so I was able to work with two other seniors before and after today's practice. They showed me exactly how the gap between ranks isn't just about remembering the moves of poomsaes and self-defenses. The gap between Bocho Dan, 2nd Dan and 3rd Dan aren’t just separated by 2 and 1 belt each, respectively.” They’re separated by constant repetition and practice to the point where everything up to that point is 2nd nature, almost like breathing. Where I'm still trying to remember everything, they just know it.
