Are you implying that stuttering is psychological? I agree there is a psychological element that engages in a vicious cycle with the stutter. But that doesn't discount our stutter. The stutter is a problem that we have with our speech. Our disfluency isn't a result of a trigger. So let's apply this analogy to my experience with achieving fluency. Dad doesn't get to come into the dojo. Dad can keep nagging me outside of the dojo. At school, in the street. Everywhere I go. But every week at the dojo, I take my lessons. I learn how to stand. I learn how to breathe. I learn how to move my arms. Etc. All things I already knew how to do. But I learn them anew. When I get up in the morning, in the privacy of my room I practice. I commit myself to learning karate. My sensei guides me and corrects my forms during my lessons. I continue to practice daily in private. Regardless of the nagging, I'm developing that skill. I'm advancing through the ranks. Developing the muscle memory. The moves come fluently and automatically. How I stand, how I breathe, and the forms that I learned as a white belt have evolved. Take your stance as a simple example. The white belt stance is basic. Meant to teach you how stand in a manner in which you won't fall over while doing basic forms. Once you achieve fluency, you're not going to be using that same stance. That white belt stance was strictly for training purposes. Before we ever demonstrate our karate skills, we've done two things. We've grown confident in our ability through practice and training. Any nagging has been discounted. More importantly we actually developed the skills. We're fluent in martial arts.
