Here’s an observation, three suggestions and one tip for when you’re on TV.
The green room is not green. I’ve been in (I think) four green rooms waiting to be on the air and none of them have ever been green. All of them have been called the green room. Weird.
1. Sit up straight. Even if they sit you on some kind of ridiculous couch six inches off the ground, do not lean back into the cushions. You’ll look like a lethargic drunk. In the same way, do not lean forward and prop your elbows on your knees or you’ll look like an animated drunk. Instead, prop the edge of your butt on the very front part of the couch, fold your legs off to one side like a librarian and sit like there’s a book on your head. You will feel stupid but look less stupid.
2. Accept that the way you look on TV is actually the way you look. Sigh.
3. Don’t move your lips along with the teleprompter while the host is reading it. It’s tempting but unprofessional.
Save the video and watch it in 10 years. You’ll be much happier with your appearance.
