I have been public speaking since school. Our team won a local schools competition. I joined the debating society at university and did quite well, and I have been doing it ever since. To be honest I enjoy it
The first few times I did it, I was in a total panic, but gradually got used to it. Now there is always an element of stress. But I think that is necessary.
Going back to the schools competition, our team of convent girls beat a team from the local boys private school. The reason they lost was because they were so laid back and so confident that they could beat this bunch of girls, but we were keyed up, nervous -and determined to win. Nervousness, but not too much, is a good thing.
