Believe it or not, fear of death is actually second to the one greatest fear that the majority of humanity seems tensely afraid of: fear of speaking in public.
If fear is all that you are thinking, then forget about that presentation that could earn your company and you the necessary sales. Presentation and public speaking is one of the most efficient as well as effective manner in making your products and services known. Why deny your product or service the chance to be heard? If you are still afraid, try your very best to focus on the various positive after effects of making that presentation. Create in your mind the numerous clients, customers and contact persons you might not get to see or be involved with if you let that unnecessary and irrelevant anxiety take hold of you. Your presentation may only take thirty minutes but the long term effects of your pitch or presentation might go a long way.
If the fear is still gripping you, try to do the following exercises to help your body relax and warm up to whatever it is you plan to do in your presentation. Turn that negative energy into a positive one and see who benefits best from it.
Warm up your body. Are you wearing high heeled shoes now? If you are, please take them off now. Then go and stand up. Try to stand on only one leg. Then shake the leg that is off the floor. Switch legs and do the same thing again. What you are doing is taking the negative energy of anxiety towards the floor and out of your body. Though this may appear and sound so out of this world, it actually works. For your information, actors use this as a warm-up exercise prior to attacking any scene.
Hold out your hands, shake them, fast. Put your hands over your head and bring them to your sides. Repeat the same process. Doing this continually will take the tension off your hands and arms so any movements you make with them during your presentation will appear natural.
Ease the tension present in the muscles of your face. In order to do this what you could do is chew in a manner that is exaggerated.
These exercises are done for the purpose of warming any part of your body that is edgy, uptight or taut from being too nervous thinking about how you will do in your presentation. Do not think too much though as it only adds unnecessary stress. Relax and your audience will relax along with you.
