Institutio Oratoria

On the other hand, I am not unwilling that the man who has got to make a speech should show signs of nervousness when he rises to his feet, should change colour and make it clear that he feels the risks of his position: indeed, if these symptoms do not occur naturally, it will be necessary to simulate them. But the feeling that stirs us should be due to the realisation of the magnitude of our task and not to fear: we should be moved, but not to the extent of collapsing. But the best remedy for such excess of modesty is confidence: however great our natural timidity of mien, we shall find strength and support in the consciousness of the nobility of our task.
