You write a speech with confidence and things that make people understand and and feel the message you are trying to get across. Always focus on the topic you are talking about. Don't exaggerate and add things that don't go along with the speech. Keep it short, keep it simple, and easily written. A speech shouldn't take too long to write. Speeches should take up 5-10 minutes. Keep the message or point you are trying to get across as simple as you can.
