I am not trying to be disrespectful, but unless you are a speech therapist the possibility of you knowing several people who stutter is highly unlikely. Only one percent of the world stutters. Many people go through life never hear anyone stutter. You did make some good points. As far as phycological tricks, we call them self hypnosis. A book by Melvin Powers," Guide to Self Hypnosis" has helped many people. Saying auto suggestion daily is great to improve anyone's life. Only people who stutter knows how other stutterers feel and what they go through. Again, no disrespect.
