I know that I'm very late to this thread, but I was hoping I could offer my experience with extroversion:
Attempting to be extroverted for public speaking seems completely unnatural for me. I had to speak in front of an audience and a school board once and it's difficult to describe how awful the experience felt. I had something prepared, but for whatever reason I decided to go off-script at the end and speak from the heart and I felt my voice crack and my pulse go through the roof. Although my supervisor/adminstrator told me that I did very well and that my speech was "right on the mark", I re-played the experience over and over in my mind every so often for the next few months. "Why on earth did I say
that?" I kept asking myself.
Fast-forward a few months and I find myself taking courses in educational administration. I sometimes question why I enrolled in the first place, but I feel like I have learned some valuable lessons already in just the first few weeks of my courses. First of all, having a little more college experience than many of my classmates, I feel like I have taken on almost a shepherd role, and I don't mean that to sound arrogant at all. I just see some of them struggling and I find myself doing whatever I can to help them.
In one of our classes, we have a professor who just recently received her PhD and she has been very hard on all of the students in the class; it almost feels like she wants to throw her weight around since she has a PhD and we don't. She has changed the syllabus multiple times and her expectations are unclear and demeanor is simply unkind. When she gave us a final project that everyone in the class felt was unreasonable, I found myself being the only person who tried to stand up to her and express the feelings that most of us had. The strange thing was, in this case, I didn't feel like I was "pretending" or trying to be something that I wasn't. I felt like I was assuming a role that had to be taken.
This leads me to a final comment (if you're still reading). I have taken the Meyers-Briggs test multiple times because I wanted to figure out if I was truly an INFJ - I guess I felt like I let my desk or my office become too messy most of the time to be a J and not a P. Anyway, the point is that according to Jung and Meyers-Briggs, I probably am an INFJ. That being said, just because I'm an INFJ doesn't mean that I should be scared to assume an "extroverted" role. For so long, it was easy for me to say, "I'm an INFJ so I wouldn't be good at doing that." I was letting my personality type set parameters for my life. I am at a point now where I want to say, "Yes, I'm an INFJ, but that doesn't mean I can't get better at speaking in public or something else that requires more extroversion." As an INFJ, I cringe at the thought of "faking" something. I want to be authentic in everything that I do. I want to get to the point where I can still be myself when I am speaking in front of crowd, and the only way to do that is to get over the fear and just practice it. If INFJ's are dolphins, I want to be the dolpin that gets out and lives life, not the one hiding underneath a rock (although I will still probably need to go there every once in a while just to recharge!).
Anyway, sorry for that rambling everybody
I am glad that I found this thread and want to the thank the original poster for thinking of it.
Sending all my happy thoughts,
