I'm also someone who is told to "be more extroverted," but I attribute that more to being a woman in a field that's still dominated by men. And, well, it's true -- I do need to be more outgoing, and I appreciate the comment because the people who tell me that are people who are trying to help me.
I've never seen a major "Asian-American character" played on any mainstream TV show. Rather, there are Asian actors in generic character roles, and maybe for once, I'd like to see a role with an unabashed Asian or Asian-American character that shows some element of culture?
