overcoming shyness

I am determined not to allow myself to be limited by my fear of interacting with people. Whether I was born with an inclination towards social anxiety or whether I happened to develop it, I'm desperate to overcome it.
What on earth do I have to be afraid of? 1) Nobody will show up. The average audience size at the Edinburgh Fringe is four. Four people. My venue seats 200. With 196 opportunities to fail, nightly, this season is going to be downright sacred.
There must be thousands of other people out there who also live with the secret shame that is shyness, the most prevalent of all socially transmitted diseases. I hold out hope that one day there will be a cure as opposed to the band-aid solution that is a wide-mouthed funnel and a litre of gin.
