Turn your piece of paper sideways and put your main idea in the center of the page. Draw an image to represent this idea. It will help your brain to have a visual stimulation.
Draw branches from the center and write your main points on each one. Use a branch for your introduction, one for each of your main points and one for the conclusion. Try to use a different color for each branch and use images as well as words- this use of color will help you to remember the information when your deliver the speech. Draw curved branches rather than straight-lined; curves are easier on the eye and, according to Buzan, may inspire your thinking more.
Draw secondary branches from your main branches. Use them to record your ideas about each point. They will form your sub-points when you deliver your speech. Draw images as well as using words to visually stimulate ideas.
Write only one word per branch. Single words are less restrictive and may help to spark even more ideas.
Make a new copy of your finished mind map. The first draft is likely to be messy from generating and revising your ideas.
Practice the speech using the new draft of the map. Introduce the idea at the center of your mind map. Follow the ideas outward on your map. Each colored section shows a different part or section of your speech. When you have covered a section, connect back to the central theme and move on to the next colored section. Unlike using linear notes the words, short phrases and pictures allow you to visualize the speech as a whole.
Take your mind map with you when you deliver your speech. Look it over one last time right before you deliver your speech, and keep it in front of you during the speech so you can glance at it as needed.
