Self-confidence is essential. Never doubt for a moment that you have it within yourself to make a great speech. You can move your audience. You can sell them on your point of view. You can even make them laugh, if that's your goal. Lack of confidence is a common problem with beginning speakers. Even Moses lacked confidence in his speaking ability. The Old Testament relates that when God ordered Moses to lead the Children of Israel out of bondage in Egypt, Moses tried to beg off, saying, "Oh, my Lord, I am not eloquent, either heretofore or since thou hast last spoken to thy servant; but I am slow of speech and of tongue. . . . Oh, my Lord, send, I pray, some other person."
And so the Lord sent Charlton Heston.
