These are EXACTLY the points that make me stutter less (or more), but there are a wide variety of types of stuttering and for others this might not work. I am a medium to light stutterer depending on the phase and I observed that for me it depends heavily on my psychology. For example I always stutter in a certain bar I regularly go to where I had some really bad stutter related days. That kinda reinforces itself and when I go to the bad I know I will stutter and automatically label myself. Or this one time I was backpacking on another continent and in a completely different context, I didn't stutter once the entire trip. When I was back I begun to stutter again immediately.
