I am a musician for a living. I've always been fine performing. It feels like anything else to me, I just do my thing as it were. When people talk about things like stage fright I just stare at them, I don't understand it at all.
If it's an issue of confusion then why not work on learning how people work?
"I may not be smart enough to be afraid of people." This statement doesn't quite make sense, can you indulge me and explain what you're talking about?
