Which word produces positive of negative images - extrovert or introvert. I would hazard to say that the general populace has a negative perception of introverts - meaning there is something wrong with being an introvert.
Myers/Briggs has Introversion and Extraversion as the first letter in their personality test (e.g. INTJ or ENTJ etc). Talk to any Introvert (that is if they are willing to talk) and they will indicate they feel guilty about the number of friends, acquaintances they have. Or that they should be interacting with others more. Is this guilt just the conspiracy of extroverts putting pressure on introverts? Or is it a self inflicted pressure inside the Introvert forced into a world that values extraversion?
My Myers/Brigg profile is and INTJ with a close call on the I and E. I can get "energy" in solitude and in social settings. What I have learned over time is to minimize any guilt of my inner need to recharge with introversion. I don't measure number of friends, acquaintances, network contacts, Linkedin & Facebook friends etc. etc.
What's the right dose of I and E. Remember moderation in all things :)
