Nervousness is probably the biggest problem to be surmounted for most in-experienced speakers. Nervousness seems to disable common sense, and normal intelligence gets swamped by anxiety. Nervousness is a very real problem, and is the root of most of the other problems with speaking. We all talk competently in a group of friends, but as soon as the group of friends becomes a wall of strangers, nervousness usurps our every-day competence, and we need the prop of advice.

Speakers, who have similar problems, can benefit from the knowledge and techniques gained from these studies. (David A. Brown, 1997).

Compared with the calm competence of every one else, he or she feels their own shameful failure as a personal inadequacy. The truth is that nervousness when facing an audience is very common. Almost everyone suffers from nerves, even experienced professionals, and the reason why we are not aware of this is simply that the basic effect of nerves doesn't show. Providing the gestures are controlled, butterflies in the stomach are invisible to the audience. So the calm and confident speaker you watched with envy, was almost certainly trembling like a leaf inside: you just couldn't see it..................
