You have to have a topic for your speech.
- Pick a topic you know something about or want to know something about.
- Pick a topic you are interested in.
- Remember your audience - they have to listen to you!
- Andrew Dlugan in his Speech Preparation Series states
"a successful speech is one where the audience receives the message."
