1. Prepare: The more you prepare and the better handle you have on the material you are presenting, the better it will go.
2. Practice: Once you have prepared, you MUST practice, early and often. Rumor has it that Churchill practiced for one hour per one minute of speech content he was delivering. 5 minute presentation = 5 hours practice. How long are you practicing?
3. Check out the Room: Familiarity breeds comfort.
