Introversion is an asset if you are the kind of person that carefully analyzes situations before acting.
Usually it's a double edged sword, same as extroversion. Introverted people (like me) are usually labeled as "shy" when young, as if that's an entirely bad thing. But even when I was little I knew I was mostly just being cautious. I read people very well and don't make friends with people of questionable character who I can't trust. I love to imagine and think a lot, as I always have. I'm not artistic in the sense of music or with a brush, but I am very creative and always have been. Over the past few years I've been directing my creativity specifically to writing, albeit slowly as I have a lot of other interests and work plus church takes a good chunk of my time.
I also absolutely have a deep aversion to phony-acting, insincere people, and don't like to put on a mask myself. I'm as straightforward as it gets, but without being blunt (usually). I don't like smalltalk much, but I can carry on a conversation with pretty much anyone about a lot of different subjects.
I'm growing to accept introversion as part of who I am, though it's still a double edged sword and always will be. I don't go out of my way to make friends, but I'm good friends with a lot of people, and build friendships a little bit at a time.
