Rhetoric Day 154
Even the best speakers, they who speak with the greatest ease and grace, appear to me almost with an air of impudence, unless they compose themselves to speak with a certain bashfulness, and are under some confusion when they set out; yet they can never appear otherwise; for the more a man excels in speaking, he is the more sensible of its difficulty, he is under the greater concern for the event of his speech, and to answer to expectation of the public.
- Cicero "De Oratore"
