One of the worst things, in my opinion, that a person who stutters can do is to try to stop stuttering. In my experience (43 years as a person who stutters), the times I have tried to control my speech, even my emotions about speaking, I've stuttered worse than I had before. Probably more useful to deal with related issues that you have more control over, such as confidence, self-esteem, understanding that stuttering is what you do and not who you are, moving on with your life, etc. Yes, I stutter, but I am also a salesman, a husband, an investor, a friend, brother.
