Public speaking is not an art, nor a science. It's a question of mind over mutter. Overcoming a biological block. It's like peeing in public. The harder you try, the more Mission Impossible the job becomes. Blather and bladder are inextricably linked. It's a matter of doing what comes naturally. The more self-conscious you are about it, the more you try to force yourself, the more you literally dry up.Thus spake Jug Suraiya.
