I think I know what you're getting at. Most of us seem to be very observant, especially when it comes to exaggerating reactions, as well as sensitive. These are great traits for actors or actresses... If there weren't people staring at me, and If I were able to not hear myself, and if there was no stage (I don't like stages) i'm sure i'd make a half decent actress. But without social anxiety, I wouldn't be as observant from all my wallflower years either, so it's not really possible.
