I also made the mistake for most of my life of pointing the specter of self improvement and reflection only inwards. There is a lot that this can accomplish, but the task will always be deficient. I feel like this is something that extroverted people take for granted and come to expect. It can be a very draining process for an introvert to fully participate in self reflection through others, but at the same time it is probably much easier for us (introverts) to see it as such and use it to it's full potential, deriving meaning from much more subtle things that an extrovert would gloss over.

Like so many other things in life, I feel like I always had this knowledge derived through basic knowledge and experience but until recent years didn't understand the scope and power of it. I feel like my life has become much more meaningful and rewarding since discovering the depth of the interpersonal mirror. The irony of this is that I took a class on interpersonal communication to "improve" my introversion many years before this discovery and there was no mention of such a thing.
