How confident are you about addressing a trade group or seminar audience?
Even though I've had speech classes and extra training in presentation techniques, I used to be nervous about speaking in front of groups. Yet I found that preparation, practice, and knowing my subject helped me overcome this. I've also found that the world won't wobble on its axis if I admit I don't know something. An audience can sense when you're bluffing―what you convey overpowers what you say.
Now, within the first few minutes, I'm consistently able to develop rapport with my audience, and it's no different from talking to you like I'm doing now. I know my material and present it in a logical, organized, and interesting manner. When people accept the messenger, they accept the message. That's what teaching is all about.
I am comfortable presenting my material in an informal setting, such as this meeting, or to a smaller group, like a staff meeting. However, extemporaneous speaking is an essential communication skill. I'd welcome the opportunity to learn more about how to present ideas effectively.
