Where the speaker is correct is that nothing can hold a candle to authentic passion. So though your feet may never stop moving during a speech, although I hope they will, and your mouth may move at 4,000 words per minute, although I hope they don't, if you focus on the audience and giving them value, from your HEART, you may be on the path to a great speech.
Let me share with you, from my own observations, training, and experience (thousands of hours), 7 secrets for a great speech.
1. Focus on the audience
Many studies report that public speaking is more feared than death for adults. That's because so often speakers are focused on their own perceived inadequacies, lack of knowledge, lack of speaking ability, or dislike for public speaking. If they would stop focusing on themselves and instead focus on what they know and how to give the audience value, they can relax. It all starts with wanting "to bless, not impress" as Stephen Covey put it.
Study the topic, organize the information simply, and deliver it in your own unique voice. You were asked to give the speech to impart valuable information to the audience, not to hear yourself talk. In other words, you're not there for you, you're there for them. Focus on them.
A common misnomer when giving a talk is that you've got to be Jimmy Fallon funny. Indeed, a great speech is entertaining, but not always because the speaker has Tina Fey good looks and wit or this gentleman's down-home charm and humor. Most often it's because the speaker realizes what is most important to the audience and delivers it in a way that makes sense to them, while letting their natural passion shine through.
2. Connect with individuals
You've heard the popular advice that to avoid getting nervous when speaking in public you should imagine the audience in their underwear. I'm guessing the thought behind doing so is that it puts the audience in a more human light. Though I understand the supposed intent, it promotes the wrong focus.
Rather than reduce the audience, almost denigrate them as it were, why not imagine them as friends, as people who want your speech to go well? As people genuinely interested to hear something on the topic you're about to share.
Virtually no one, and certainly no one whose opinion matters, walks into a speech hoping the speaker will be boring or embarrass themselves. Most audiences arrive ready for the speaker to succeed and are willing to give them their attention (the other 6 secrets will allow you to hold that attention).
I received some excellent training years ago about connecting with individuals. I used to scan, not even look at, the audience at a pace to rival Usain Bolt's fastest times. I didn't look at people. I just scanned the audience at large. I'm sure that made audience members feel special and helped them connect with the material, just as I am sure a shark bite feels like a feather tickle.
The person coaching me suggested I pretend I'm pouring tea (or lemonade) into a person's cup. Look at that person for the length of time it would take to pour a cup of tea, or to complete a thought. Then move to the next person with your eyes, make eye contact, and fill their cup. Next person and so on (not moving down the row sequentially, but moving to another person in the audience). In this way, you are connecting with individuals, real people, one on one, which is what master teachers and speakers do. You are sharing a piece of you with them. It's the best way to be present in your talk.
