With preparation and practice you can replace your panic with poise!
Recently I met yet another adult who confessed to a lifelong fear and dislike of public speaking. Like many of you his fear began with an unhappy childhood experience of being forced to prepare and deliver a speech in front of classmates.
He went through school and university avoiding any classes that required participation. Some students thrive in speaking in front of their classmates. I feel blessed to have been in that group, although one-on-one I was introspective and shy.
