The better that you organize your material when preparing your speech, or other presentation, the easier it will be to deliver.
One technique that I use is Mind Mapping, popularized by Tony Buzan. It’s a method of organizing your material and relating the different parts to each other in an understandable way.
That makes it easier to keep the speech in a logical order and to focus on the material so that it fixes better in your mind.
With a Mind Map, you put the central topic, or thought, for your presentation in the center of a large sheet of paper. Think of the main sub-sections of your talk and put them inside individual circles on separate spokes which radiate from that central topic.
Then you can break each section down in to sub-topics. They go on spokes that radiate from the relevant subtopics in your diagram. This makes it very easy to;
• see relationships between particular sections,
• notice any important areas which you had not put in your original plan and
• decide the best order in which to present your material to that particular audience.
