It is too late to think about the cut of your coat when once you are upon the platform, so centre your interest on what you are about to say—fill your mind with your speech–material and, like the infilling water in the glass, it will drive out your unsubstantial fears.
But they cannot be mastered and applied by thinking or reading about them—you must practise, practise, PRACTISE. If no one else will listen to you, listen to yourself—you must always be your own best critic, and the severest one of all.
never hurts a fool to appear before an audience, for his capacity is not a capacity for feeling. A blow that would kill a civilized man soon heals on a savage.
