Now that I've read Jung’s *Psychological Types*, I think in the original Jungian definitions of introversion and extroversion. Trying to find anything relevant to them is an exercise in frustration because everyone uses the popular psychology definitions (e.g. "prefers solitary work" and “prefers group efforts”). I am primarily introverted by both definitions, but I want to find some information based on the original, and it's nigh impossible.
