You have to get out there and do it — everyone has a story to tell no matter who you are. I think ti’s important as you say to get out there and doing it once you get over the attention bit. To be honest, I am not an introvert, but I don’t specifically like all of the attention.
I remember a boss of mine who was the MD of the company is an introvert. She had to learn to become extroverted as part of her job — she told me how hard it was, but once she practiced and got used to it, it worked. She is very successful, and she also became a get storyteller too!
