To become a talk show host, you need to be a reader of people, one who can elicit the highs and lows of both guest and audience.You should also have an ample dose of confidence, because a nervous or shy talk show host is something of an oxymoron. If your preferred venue is radio, you should be very comfortable with a visible audience that consists only of a microphone, an engineer, and perhaps a call screener. You must adore the sound of your own voice. If your medium is television, and includes a live audience, you must have charisma, stage presence, and the abilities of a talented actor.
