PUBLIC SPEAKING WISDOM FROM ORISON SWETT MARDEN:
Self-expression in some manner is the only means of developing mental power.
What is technically called 'stage fright' is very common.
No public speaker can make a great impression until he gets rid of himself, until he can absolutely annihilate his self-consciousness, forget himself in his speech.
Every time you rise to your feet will increase your confidence, and after a while you will form the habit of speaking until it will be as easy as anything else.
It is not the speech, but the man behind the speech, that wins a way to the front.
