This will continue to improve. Today it is a 30-minute conversation with your manager, tomorrow it will be an hour presentation in front of your whole department. That is the beauty of our methods, the speed at which you cure is how hard you are willing to work. We have had people completely cure within a couple of weeks and having just read the book.
What people do not understand is that curing is not a one-day thing. You will not read the book and be cured on the same day. It takes weeks of practica, and each day you will stutter less and less until the day you think to yourself “I have not stuttered in a month!”
Keep up your hard work and you will be cured within weeks!
