Keeping a notebook of ideas and clippings is a good idea. If you have strong feelings about your topic, it will be easier for you to speak with conviction. You won t have to manufacture energy. You will be making a ten-minute speech so keep the topic narrow enough for this time constraint. It s better to be more detailed about a small bit of material rather than skip lightly over a lot.
Specifics are stronger than generalities.
You should write this out as a complete sentence. This helps you clarify your objectives. Test your statement. Make a subject outline for your speech Write the general and specific purpose at the top of your outline. Chunk together your ideas.
