That first task doesn't sound too bad. More often than not, I catch myself without a single thought in my mind. I usually fidget with my hands in some shape or form. In saying that, I don't know if I could go even an hour simply doing nothing. I understand it's a form of meditation and is supposedly helpful, but it sounds boring too, lol. I'll give it a shot when I can, I imagine it's a daily task as well. That final thought of yours, I do agree with. I have seen others mention it in a similar way where they believe a tragic/traumatic event has caused their stutter to develop, and tbh that could be a similar case with myself. I do believe the subconscious mind picks up on a lot of the negatives and perhaps tries to protect ourselves from those same experiences, in a sense. Or it picks up on habits and develops them further. Either way, it definitely is a psychological issue, and I do believe it can be fixed the same way it came out of practically nowhere. All I know is that I didn't stutter, some life changing events occurred, and I slowly began to stutter after years of such events. My life events haven't been too bad in comparison to others, but things can affect everyone differently. I appreciate your advice and will try to take part in the task. Thank you!
