All it requires is some commitment and hard work. You gotta be consistent with it. Try as many different programs/ strategies as you can, and figure out the most suitable one. Before doing all this, remove a very common misconception: There is no QUICK-FIX. You will be there one day, and we all know that learning is something that fluctuates. I wish you the best of luck with this stuttering journey of yours, and if, ever at some point in time, you feel like talking to someone- be it on the phone or the text- don't hesitate to reach out.
