This whole "spectrum" thing is nonsense. Classifying people in such a grossly simplified way is like dividing the brain into "left" and "right" which was only some eye-grabbing stunt which totally misses the essence of the issue. What matters in constructive work is the ability to present one's ideas clearly, coherently and convincingly, not the habit of hanging out with people and keeping your mouth open all day. I think somehow a lot of concepts get these two things mixed together. A lot of people are absolutely fantastic in communicating their ideas, engaging in conversations and contributing their unique insight in a manner that makes everybody else get what she's trying to convey in no time. However such people might not be the type who parties all day long outside of work, and might instead enjoy reading or creating something on her own while idle. I don't see the least bit of problem in that and I think those people will well succeed in business settings, in fact they can well achieve greater success than those who only talk and don't reflect. I'd even argue that every person who has achieved something must have spent a lot of time on her own, learning and reflecting upon various things, instead of wasting her time in trivial social activities all day long. Now, what we usually call "introverts" are people who can't express their thoughts well, who sometimes can't even pronounce words cleanly, loudly and with confidence when ideas are needed. They tend to be quiet at formal group settings and say nothing at all even though they might have already thought of something. That's really just a lack of ability (totally acquirable) instead of "personality trait" or whatsoever. The type of person I mentioned in the previous paragraph also don't necessarily enjoy talking all day long, but they make a hell of a talker when the time is right. So, differentiating people based on whether they "enjoy being together with others all the time" is just such a totally laughable and nonsensical concept. And to say people should "act like" an "extrovert" is just some other oversimplification BS. Act like a pro who can present ideas expertly, not a brat who only knows to party all day and crack irrelevant "jokes". What those real "introverts" need is indeed some help in getting themselves at least able to express their thoughts with clarity and communicate with others in a group setting. However, to say that successful CEOs etc. are such "introverts" is really a gross mischaracterization and something totally missing the core of the issue.
