Remember that the audience is interested mainly in your message
Your task is to give the listeners what they expect. The focus is not on you personally, but on what you say. Your listeners don't know how nervous you are or that you slept poorly the night before. They are looking forward to your message.
If you stumble or forget something in your speech due to nervousness, they will understand and will not judge you.
Get to know the audience before your speech
Don't hide behind the scenes. If possible, before the speech, go around the room, shake hands with the audience, introduce yourself and thank them for coming. Making the faces friendly and personal contact will help you relax.
Remember that people are not machines
Even the best speakers make mistakes. When this happens to a president, media will jump on it. When you make a mistake, it will not be so terrible.
Relax and feel free to laugh with the audience if you stumble. You should realize that the people in the audience are human just like you. They may suffer from the fear of public speaking as well and admire your courage.
Don't be too hard on yourself
Many people demand much more from themselves than others would demand. Your speech is not really a matter of life and death, you do not have to ask more of yourself than your audience asks of you. Try to stay as calm as possible. Get a good night's sleep and eat a good meal.
Then be yourself during the speech. Share your knowledge and passion for the subject you are talking about. Take the audiences' interest in your knowledge as an honor and a pleasure.
