I’ve been doing this since I started stuttering, I have always been a prodigy in maths, Now I am in the university, 5 semester of industrial engineering, and I still been one of the best in my career, don't let the stutter takes control of you live, you have to take control of your stutter, think about it, the most people who stutter often have a superior IQ, think about how you are letting that brain waste, just practice and practice and practice, put yourself in a social situation and no matter if you stutter, just practice and practice and it eventually will improve
