Here’s a short, but really powerful tip.

Give a subject two segments (in Talk radio), MAX.  If it doesn’t “catch fire” by then, give up and move along to something else.

The same principle is true in Music Radio – give a subject two tries, and if there’s no usable reaction, punt.  If it hasn’t “happened” by then, you’re just firing bullets into a dead body.  This is both boring and desperate-sounding.

This is why I always over-prepped each day.  Just having “enough” to cover a show might not actually BE enough on a given day.  And as you know, it’s impossible to predict when something might inexplicably fail to connect with the listener.  (Although, now that I think about it, this could simply be because there’s not an Emotion at its core.  Might want to think about that, too.)
