At different times in my life I have expressed one side of the currency more than the other. Tapping into my extrovert side was inherent in raising a family and in succeeding in my career. In fact, teaching kindergarten calls for more non-stop extrovert energy than most jobs. Just try to going into your own space with a class of five year olds milling about!
These days I am accessing more of my introvert side. Is this a life-stage tendency or personal propensity? I think both. Although I like to be alone, I also like to hang out with family and friends and to visit people, many of whom can’t get out and about on their own, and thus have lost some of the choice that I take for granted.
