As a Public Speaking instructor I readily come in contact with students that are terrified of speaking in front of the class. Some speakers tremble and some uncontrollably shake. Some speakers talk extremely fast and some go blank. For some speakers it's their hearts that race and others become red in the face.
Many people do.
The following material includes tips and advice to help you reduce your anxiety associated with speaking in public. The reason most people get anxious when required to speak to a group is that they are afraid of looking foolish or stupid in front of many of their peers and important people. They are afraid that their mind will go blank or that their lack of speaking skills will lower the opinion others have of them. Being humiliated can destroy a person's ego and confidence. It can really ruin your day too.
