I think you are right there. Confidence, life goals in motion, on the right track, this helps so much with stress. I made a video about it that I just posted on here but my best advice is not to even think about it. I know it's an odd concept because you want to conquer it but the best way is to not let it get to you and let it get better on it's own. We don't know what or how it's caused but we can control or reactions to it to an amazing extent. We can also control how it "looks" by what we do when we are in a block. How we sound during a block and what we do physically. Those choices are yours to make but if you don't dwell on it after the fact, that's when you begin to conquer it in my humble opinion. As you continue not to even think about it, not to even worry about how it looked or what others might have thought (who are likely far too busy thinking about themselves anyway like we all are) then it gets easier, it gets less severe and as with my case it's all but gone. I don't even remember when I stutter anymore and it's so minor and easy to fix. By not stressing over it, it doesn't grow, it doesn't continue, it just might happen and it ends, goes away because my mind has gotten used to not stressing it or letting me fall into the rut so to speak.
