Something else too, I agree that it’s the negative thoughts accumulated over many years of stuttering that cause a lack of confidence and make us avoid certain words and block. It’s more specifically these negative thoughts that make us anticipate situations where we’re going to stutter, putting us in a vicious cycle. I’ve already tried a lot of techniques to stop stuttering, and I have believed in them, that they’ll cure me, but in reality, in my case it’s not the technique itself that helps but the confidence it gives me because I tell myself that now I have a weapon to defeat stuttering and speak normally. In conclusion, self-confidence and eliminating negative thoughts are the key elements to speaking fluently.
