Whatever you do well, congratulations on that. I mean that sincerely. The good things that you do each day make a great impression.
Similarly, when you say things more than once (as radio continues to do, trying to beat a thought into the listener’s head), or you do “the moral of the story” obligatory recap at the end of something, or say radio clichés (like “on your Monday morning,” “Hump day”), or do something silly and outdated (like “The Mindbender Question of the Day” or “This Day in History”), those make an impression, too. As my friend and partner Alan Mason says, “Everything counts.”
So, weed the garden regularly. Listen to your own show at least once a week. Add new ideas all the time. Consistency = Good. Predictability = Bad.
Think of your show as a demo tape. Because to the listener, it actually IS.
