Yea, I think anticipating stuttering brings up fear or just stops us from flowing naturally. I recently read a short book called “Zen and the Art of Archery.” It kinda discusses becoming one with whatever we do so that we can flow naturally. And I recently have been watching YouTube videos about Lao Tzu, a Chinese Philosopher. There’s various videos about his teachings but one is about how people should be like water, flowing fluidly and being able to overcome any resistance. For us our resistance is our own selves. Check it out. I’m a Christian so don’t recommend getting too deep into the spiritual side of Taoism but these videos I believe can be of help to anyone https://m.youtube.com/watch?v=yUjPFCosmNA
