Communication Problems!

I've trained people, and it was one long explanation. Just adapt your training techniques to conversation and speaking at meetings. Try looking at it this way: You have the right to speak in meetings. That's why you're there. You're at the meeting because your input is wanted, same reason. Your views are considered valuable. People are trying to communicate with you. You can speak on your topic in the same way as you do as a trainer, making your points clear. It's almost exactly the same thing. "Impressing other people" is more likely to be a result of your expressing yourself in your area of expertise. Don't be someone you aren't. It will backfire.
