We all have short attention spans. This is exacerbated in these days of communication delivered in truncated, rapid-fire bytes.
So you have to set up your presentations so that you do something frequently to keep attention.
Change your delivery style.
Support your words with a new visual.
Challenge with an activity for audience involvement.
Tell a story. Whatever techniques you use, introduce them often and vary them.
Each will have its own impact, but make sure that impact supports your chosen image and message.

The introduction to your speech should
– Build credibility
– State your objectives
– Overview the elements
– Lead into the main point
and give a short background for the points to follow

Great speakers seem to stay on track effortlessly. Their presentations are tight and focused. Do you find yourself, on the other hand, sometimes, with too much information, or getting off the point of your story or presentation?
One simple trick to tighten and focus your presentation is to define the message; the central message of your presentation – what one thing do you want the audience to take away?
This message can be called a thesis statement or a theme. It can be given a number of names, but you need to be able to state it in one sentence. One sentence. That way you will stay focused on the outcome when you are planning.
Keep the sentence in front of you as you are preparing your content. Whenever you find a useful piece of information, ask yourself if it contributes to your one-sentence message and how well. When you are choosing the parts of your story, or the supports for your points, ask if they contribute to your one-sentence message and how well. When you are interacting with your audience in Q&A or an ad lib session, ask yourself that same question. Am I contributing to that one-sentence message and how well is what I am saying supporting it?
One sentence – one of the secrets to tightening and focusing your presentations.
