It could be a chicken and egg dilemma. But with the spontaneous people I know, they're just so good at **letting go;** meaning, they'll get into trouble more often that we do, which is expected because they don't think through their actions like we do, but they'll just embrace the pain and suffering at the moment, and completely forget about it the next moment. I think for many stutterers, we have a difficulty letting go. It could be how our stuttering started in the first place. As a child, we may have stuttered badly at one time. But unlike spontaneous people, we over-analyzed and over-introspected the situation and it morphed into a childhood trauma that permanently influenced us. Of course, this example doesn't apply to all stutterers, especially for the chronic cases with a known biological anomaly.
