I was amazed when I read an article saying that fear of death is only second to fear of public speaking. It made me think and say to myself, yes I think it's right. Even I, am afraid to speak in public most of the time before. I am even afraid to attend seminars and workshops for fear that I would be asked to speak in front of other people. But fortunately, I have learned how to manage (although not totally eradicate) the feeling of fear and nervousness whenever I speak in front of a group of people. I still feel nervous but I can survive speaking in public.
Most of the time we fear speaking with a person in authority or a person who has a higher position than us. We feel intimidated, I guess that's the correct term. But why? For me, it was for lack of self confidence and for being overly shy. When I was young, I am not an outgoing person and I would rather read a book than talk to other people. But now that I'm working, there's always a need to speak to some people and I had to muster enough courage to do that.
There's another factor that makes us afraid of speaking, it's being unprepared. More often, we are confident to talk about a topic that we know very well so that's one way that we can do to boost our confidence.
I can't give a definite advice on how one can overcome the fear of public speaking but I can say that this fear can definitely be conquered.
As Bertrand Russell said,
"To conquer fear is the beginning of wisdom".
