Why do I stutter is the wrong question! If you are eager to change, you ask "how" instead of "why?" People who stutter have a "structure" to their stuttering; oftentimes it is very predictable. An example would be when a server comes up to my table, I take a breath, look away, say several "ums," and then force out the word "h-h-h-hamburger." That is how I stuttered. How I stutter explains specific words and situations we routinely stutter on. Why is a culdesac- you drive in circles- and HOW is the highway to change.
