Make it a Story
The human brain was designed to remember stories; it was not designed to remember facts. But we can make facts memorable by attaching them to stories, to naratives - the same kinds of things that we had read to us as children.
Those stories held our attention because something was happening to a protagonist(ตัวเอกของเรื่อง), and we wanted to know how it ended.
If we want to write the most successful speeches, we will find the stories in our subject matter. Pull out those stories, arrange the details and the information that we're trying to get across into the stories.
If we do that, we will not only find it easier to remember our speeches, but the audience wil also stay with us more closely, pay more attention, understand it better, react with greater grief or laughter or interest, and remember it better.
If we wil do this, if we will seek out the narrrative, we will find, First of all, that our speeches stay in our mind more clearly; Second, that our audience will be with us, and because we're tellling stories we'll spend more time looking straight into their eyes and keeping them with us; and Third, that when the events are over, years later, after we may have forgotten the occasions and the speeches, we will be met by the people who thank us for telling that stories and let us know how much it's meant to them.
