Most Helpful Girl
Read Dale Carnegie.
I was/am exactly like you, and there's nothing wrong with it! But the world is much kinder to extroverts in general, so it's helpful to be able to be comfortable using that personality. I've found that empathy is everything. When you can see things from other peoples' perspectives, see their insecurities, it's easier to be confident and reach out to be nice to people. I break out of being shy when I see other people that are shy and I want to make them feel more secure.
