Many of us deal with shyness and social anxiety on a daily basis. One way to be more comfortable in challenging social situations is to act out the role of an extroverted character that we create in our minds.
GloriaG at weblog Beyond Shyness and Social Anxiety highlights Daniel Tosh, who has overcome his own introversion to become a wildly successful comedian. To connect with his audience, Tosh creates an extroverted character in his head, and then imagines himself as that person when on stage. Obviously, most of us aren't accomplished actors, but that doesn't mean we can't use the same technique:
If you want to try out a personality, do it! Go to a bar or a store and act like someone totally different from yourself. This will be a unique experience, so see how it feels. You never know, you might like the rush of talking to people in a way that isn't so personal to you.
In the long run, it's probably better to break your shyness habit, rather than hide behind a mask, but this trick could be useful in a pinch if you find yourself at an uncomfortable social gathering.
