With the preliminary information researched and filed in the gray matter of the little box atop your head, it is time to start writing.
Start with the body and work out.
The BodyWrite down your main points. It should be about three and no more than five main points. Write them in a list or outline form.
With the list in place start to think how you would like to present it. If your main points are some sort of food to be served as part of a meal, how could you prepare it? Would you barbecue, fry, deep fry, bake, broil or boil?
The main points need to be prepared. Rather than cooking them, you will use words to finish the preparation. This can be in the form of proofs, demonstrating problem and solution, question and answer, or story and moral.
Use your five helping friends, who, what, how, why and when.
Once you have put it together, let it cook so to speak, by meditating on it. Think about presenting the material, the audience and your most wanted response.
The Introduction
Now create an introduction. Use your words to capture your audiences attention. Additionally use the introduction to tell the audience what your going to tell them. It may be an explanation of the organization of the material. It could be the start of the story.
The Conclusion
Wrap the speech up and to bring the speech full circle. If your goal is to motivate or persuade, make sure you have a call to action. If your speech is informative or teaching, summarize the points and the purpose.
