But if you look into it you’ll see they suffered, especially when young, with ridicule from others and self doubt. I’ve been fairly successful myself, and given lots of speeches, but the ghost of the stutter is always there, threatening me. That’s pretty much universal among stutterers from what I’ve read. Having some tools that help me address it, when I am willing to put the time and effort in, is what helped me.
