A fundamental truths about nature is that time is serial. It just passes by. Most of the time, that's not a problem. When we read a book, for example, we are in control of the pace with which we process the information that we read. We can slow down to read less in a given amount of time. We can also skip ahead or turn a few pages back to reread some information that we need to refresh. But when listening to a speech, we can’t do any of that. We are not in the driver's seat. The speaker is. If she's driving too fast, we'll miss the point. If she's choosing a bumpy road, we're probably not going to enjoy the ride. And if she's driving too slow. We're likely going to fall, well, asleep. So as a speaker being aware of that helps a lot in making the ride more enjoyable and satisfying for our audience. Keep in mind, though, that not everyone enjoys the same kind of ride. While some love the feeling of a sports car, others prefer the feeling of a well-balanced limousine. But the thing to keep in mind is that, as a speaker, you are in the driver's seat. And the more enjoyable you make the ride for your audience, the better the chances to make an impact. Keep lighting the path!
