In public speech, as in electricity, there is a positive and a negative force. Either you or your audience are going to possess the positive factor. If you assume it you can almost invariably make it yours. If you assume the negative you are sure to be negative. Assuming a virtue or a vice vitalizes it. Summon all your power of self-direction, and remember that though your audience is infinitely more important than you, the truth is more important than both of you, because it is eternal.
If your mind falters in its leadership during a speech the sword will drop from your hands. Your assumption of being able to instruct or lead or inspire a multitude or even a small group of people may appall you as being colossal impudence--as indeed it may be; but having once essayed to speak, be courageous. _BE_ courageous--it lies within you to be what you will._MAKE_ yourself be calm and confident.
