Sometimes those being interviewed are nervous. If I could whisper words of encouragement to them beforehand, I would say, "We are interviewing you because your opinion counts. Just be yourself."
In the place where I'm working now, there are huge movie-screen-type monitors off to the side of the set, and routinely a person will catch his or her image, realize he or she is on national TV and suddenly exhibit signs of terror. On the other hand... occasionally, a guest will become so enamored of seeing himself on the screen that he will stare at himself. That makes it hard to continue the interview, too.
So the learning point is this: be your best self... maybe for you that's not wild abandon. But you're energized, you're on, you're confident, you have a message to share.
We can't wait to hear it.
