Keep on running

So you've planned your show set the times up you are going to change topic, suddenly a topic takes off and you're getting a good response. But hey! I had planned to talk about under-water soot juggling and I have set up a really good guest on the subject. Throw your plans away - if you've got a topic with legs - let it run - be firm with yourself and leave that fascinating soot juggling plan for another day.
