You’re absolutely right and this is what I did to get my moderate-severe stutter to almost fluent speech. However, my stage fright kinda shambles all these techniques but not by a lot. Anyway, the whole process of 20 years stressed me so much and with other stuff that I’m having significant physical symptoms of anxiety right now. To the point, I stopped worrying about stuttering. Managing my anxiety is the biggest thing on my plate right now.
