Ah man, what a long answer I could write. I find that (among many other factors) my stutter is quite proportional to my level of comfort around a person. For example, I stutter the most when speaking to my father and my manager. I feel pressure when speaking to them. I speak almost fluently when speaking with my partner or close friends. I also stutter more when explaining a subject or concept. These situations make me plan my sentences far ahead, which gives my brain the opportunity to think that I might struggle with a word… which ultimately makes it so. I feel like I’m rambling now. In any case, it’s comfort and trying not to plan my statements too far ahead. Edit: I haven’t answered your question… I have been stuttering since being 3 years old - I am 27 now. I think that speaking in the moment, not planning ahead, and staying calm helps the most.
