Giving a presentation or a speech usually requires standing alone before an audience. Even if the audience is made up of people you know, you may still feel nervous gazing at a sea of faces focused just on you. Try using an old trick of the pros. Focus on the foreheads of your audience instead of looking at them in the eyes. It will appear to them that you're making direct eye contact, but you will be relieved of the stress of seeing all those eyes focused on you. Although it may seem strange to not really look your audience in the eyes, it's a trick that nervous public speakers have used for a long time with great success.
