This anxiety is caused at least in part because we fear looking foolish. Because we have fear, our body produces adrenaline to help us prepare for this battle. Adrenaline does a number of things for us, some helpful and some not so helpful. It heightens your senses so that you can perform at your peak, but this sense of heightened awareness can cause a sense of unease within us. For example, you might feel shaky or nauseous.
Performance anxiety can take a variety of forms.
Hopefully these five hints will help you to control your fear and use your heightened senses to give a better presentation. You have been asked to speak for a reason. You have information that those you are speaking to want or need to receive. They have come primarily for that reason. Recognize what you do well and focus in on that.
