“ Certain people have TV magic: they fall completely apart off-camera but they are completely together on-camera. They shake and sweat before they go on, they shake and sweat during commercials, they shake and sweat when it's all over; but while the camera is filming them, they're poised and confident-looking. The camera turns them on and off.
I never fall apart because I never fall together. ”
 Andy Warhol, The Philosophy of Andy Warhol (1975). copy citation
