I'm an introvert by nature too. I've had moments when I've wished that I could be more extroverted, when I've been nervous about meeting new people, or struggling to come up with something to say in a job interview. But I've come to realize that I'm really better off being an introvert. I sometimes see some (though not all) extroverts being rude, by asking questions and then talking over people when they try to answer, or bouncing quickly from person to person to person, asking "How are you?" and then moving on to the next person before they can answer, or just blurting out thoughtless, hurtful statements without thinking. I tend to have the opposite problem. I have things that I want to say but struggle with finding just the right way to say them, and then I kick myself later when the right words come to me.
However, I have my moments, when something that has been building inside me for a long time comes out and takes everyone by surprise. I think in some ways I resemble a volcano, or at least my emotions do. They build slowly, unnoticed by almost everyone around me, until they can no longer be contained, and then, when I go off, watch out. I guess this is rather unhealthy, and it has been known to get me into trouble at times. I suppose the trick is to find the right moment to say what I need to say, in a calm way that will have the right effect. But this is hard when some people don't want to listen.
