Today's lesson comes from the actual product, not the infomercial. If you happen to be one of the millions of people who, like me, purchased one of these marvellous miracles of absorption, then you know that they are actually quite good, right up until the moment when they become saturated. Once they are soaked through, they can't absorb any more liquid.
Now apply this idea to your next presentation. You have laid out your outline, covered all of the topics that you want to cover and created all of your slides. You've got your handouts and materials and you're ready to go. Your audience starts to show up and you get an adrenaline rush. You love teaching this stuff. It's wonderful to see people interacting and learning. You get through all of your material and then think of some new point or technique that you want to add in - right at the end. You have to cover it quickly because you are running short on time.
So what's the problem? Your audience is saturated.
They're ShamWows, full to the brim with all of those other concepts, they don't have room for one more thought. And it's the end of your allotted time. They're anticipating the wind-down.
Don't be tempted to become that informercial host who says "but wait, there's more."
