With Biden, possibly you reach a point where you feel competent and valuable to other people despite your stuttering, and then that feeling. let’s you relax and focus on your work and not think about whether you’re stuttering. That relaxed going about your business helps you stutter less. Then stuttering less helps you relax even more and focus on other things. At least that’s how it was for me. I’m still a severe stutterer for a few hours in a year, but I’m mostly a mild stutterer. My stuttering is not a big deal for most people, and they don’t mind paying me at very high rate, because I’m kind and can help them.
