I’m reading a speech book to help me improve my communication skills. And I learned a couple of interesting things. The book suggests that you use, for the most part, small words in your presentation so that your message can be understood by a wider audience.
Second, is to verify your facts before you share them.
Third, when you’re talking to a big crowd, use bigger body expressions, so that those in the back can view you easily.
Just a couple of ideas to share.
