This seems surprisingly insightful - particularly the "Some Practical Tips" section at the end. It's been my experience that people with introverted tendencies are often at a distinct disadvantage in social contexts because necessary interactions that feel so _natural_ to extroverts feel like <i>work</i> to the introverts. It's impossible to keep up if playing by extroverted rules as an introvert. So... Don't! Work the angles you know, and play around with the rest - failing fast is the only way to learn.
