I think you have to have a certain amount of energy. . . . I think sincerity is very important, because you can't hide on the radio, you can't hide behind that mike. There's an old joke that if you can fake sincerity, you've got it made. You can't fake sincerity. Maybe you can in acting and movies and television, but you can't fake it on the radio.
Sublimation is important.
By that I mean, there's no point in using the first person in a story unless it's very, very relevant. . . . You have to hide that part of your ego that wants to show off. Otherwise, it becomes too much about you. . . . The ability to work under pressure is very important. And I don't think it can be taught.
