Think about what you are going to say?

Your tendency to think about what you are going to say is one of the main [underlying] causal factors of your stuttering. Fluent people don't sit around generally picturing every word of a sentence and organizing it prior to beginning to speak. And you ARE a fluent person--capable already of fluent speech in many contexts--such as being alone in a room. When you force yourself to "think about your words"--you are putting a spotlight on your speech--You are just like
everyone else--You don't need to think about your words any more than they do--- When you put a spotlight on your speech, your mind tells you --- which words, sounds, etc.--you are going to stutter on. In the case of a stutterer [virtually all of whom--"see the words coming" just before they block/stutter], "thinking about what you are going to say"-- often means thinking about WHERE YOU ARE GOING TO STUTTER.. which CREATES the issue.. It forces you to scan..and to remind yourself to "Get ready" for blocks you might otherwise have not experience. When you think about something OTHER than stuttering ,the result is far less, if any stuttering.
