Here are some additional tips for giving a great presentation.
DOs
o Arrive at least 45 minutes early.
o Start and end on time.
o Speak before food is served. I have found that speaking after eating is much like speaking after drinking. You are not as concise or quick-minded. The blood runs from your brain to your intestines to digest food and suppresses your mental activities.
o Smile. You'll look like you're having a great time, and your audience will be more likely to have a great time, too.
o If you are wearing a jacket, keep it buttoned, and use a tie clip so your tie does not slide to the right or left and make you look askew.
o If you are using a Lavaliere microphone, run the cord under your jacket or sweater so that it does not show.
