In one short sentence.
Your job today is not to shock me with comments and jokes I would never share with either my kids or my parents.
Your job is not to tell me the names and titles of songs I’ve already heard hundreds, if not thousands of times.
Your job is not to hope I’ll keep listening while you free-associate with your co-host about your life and interests.
Your job today is to be relevant, engaging, entertaining, compelling and memorable enough that I listen again tomorrow.
