I've been doing it for awhile, and so have others. We classify ourselves as either introvert or extrovert, forgetting we have tendencies towards each temperament. We tend to view our choices in life as whether they support who we are - whether outgoing or reflective - before we finally conclude, "Yes, I can do this. It's who I am." While awareness in our temperament gives us wisdom, helping us understand ourselves, this awareness is not the means to the end.
