To some degree stage fright is probably in all of us when we attempt to stand up, speak and make sense. The larger the audience often the greater the fright. But, there are things that we can do to survive stage fright and thrive. Mikael Cho has discussed this problem clearly and effectively. It is worth your time. The article is entitled "How to cure stage fright: the science behind public speaking."
That sounds really unlikely to any of us who have fought with stage fright. But, the approach will be useful when put into practice. The article is great for those thinking of taking or currently enrolled in a public address class. More importantly, we never stop learning and we are always facing situations that we wish had never come along. For example, your boss wants you to bring everyone up to date on what the company is doing in your area. This article will greatly aid you to overcome the problem. So you will have stage fright, but instead of dying on stage, you will survive and eventually thrive.
Cho point out what most of us already think: "Genetics play a huge role in how strong your feelings of anxiety are
in social situations. For instance, even though John Lennon performed on
stage thousands of times, he was known for throwing up before going on
stage for his live performances.
"Some people are simply genetically wired to feel more scared when performing or speaking in public." But, even that can be taken into account and leave you free to communicate when you need/want to.
Don't stop improving. There's a great deal you can do and it really is important to you since success often expects us to do things that at the moment we can't do.
