1. Don't say Good Morning, Good Afternoon, Good Evening or any salutations: Forget about giving your salutations. Start with an attention grabbing question or statement. Immediately give a reason why your audience must listen to you. Don't give them the wrong intention or impression that it will be another boring speech.

2. Don't memorize your speech: Don't remember word by word of your speech. Remember the key pointers of your message. You will not connect with you audience if you are busy trying to remember your lines. If need be, bring some note cards to help you. It is more important to your audience get your message than you appear to remember your whole speech without notes.

3. Don't talk about things that did not matter to you: Talk about subject and topics that matter to you, things you are passionate about or something that you stand for. Your personal stories and beliefs. Your enthusiasm and conviction to the subject will help you engage your audience easily, and your audience will be able to tell.

4. Don't speak without knowing the purpose of your speech: Always know your desired outcome of your speech or the message you want to put forward to your audience. Clarity is power. Be as clear as possible. If the speech turns out well, what you want your audience to think, feel or do.

5. Don't read your PowerPoint slides: Never, never, never read your slides to your audience, it is supposed to aid your communication to your audience. Your audience did not come to see you read your PowerPoint. If possible, don't use the slides. If you need the slides, use some pictures that carry the emotion of your message. Eg. Rather than putting 3 bullet points of global warming, put a picture that shows the death of penguins and polar bear.

6. Don't end your speech without telling your audience what to do: Always end your speech with a specific desired outcome. Determine the next step your audience should do, think or feel. It may be buying your product, join your organization or start their exercise program. Something they can do immediately after they listen to you.

7. Don't understand your audience psychographics: Always, always, always understand who you are speaking to before you speak. Different audiences has different needs, wants and desires. They have different values, understanding and experiences. Skew your words, stories and tone to the psychographics of your audience without changing the meaning of your message or your speech objectives.

8. Don't speak without interactions: Public speaking speeches must be conversational but it is not a conversation. Ask questions, rhetoric or non-rhetoric to your audience. Give them time to think and reflect. PAUSE! Make them feel like it is a personal conversation.
