For me, something like this actually happened. I still stutter, maybe a bit less, or at least I don’t really notice it anymore. And the moment I stopped noticing it, that was when the real barrier disappeared. It stopped being something that truly bothered me. From there, it became almost like a feedback loop. When you’re no longer stressed about how you speak, you speak better. When you speak better, you feel less stressed. And at some point, I could honestly say that my stuttering had, in a practical sense, faded away. Later in life, I moved to another country because of my wife. I started giving business presentations, and she acted as my interpreter. That helped a lot. I only had to say each sentence once in my own language. While she was translating, I had time to think about my next sentence. That pause made a huge difference. At some point, I realized that speaking in front of larger audiences simply wasn’t a problem anymore. Of course, I still stutter occasionally. But people focus on the information, not on how you say it. For 10, 20, 30 years people kept telling me, “It’s not about how you say it, it’s about what you say.” I couldn’t really hear that because of my anxiety. But now I’m 52, and I can honestly say there’s some truth to the idea that you grow out of it, or at least you grow into a different perspective. As you get older, it just doesn’t feel like such a big issue anymore. As for daily speech exercises, I honestly can’t even remember the last time I did one. I was always busy, studying, working, and I stopped doing formal exercises sometime in my teenage years. That’s just my experience.
