With public speaking, practicing congruence is very helpful - allowing the words to be expressed with the face and body. It helps to think of simply "turning up the nonverbal volume."

Extroverts are more attuned to social rewards, so they are more likely to flash a smile for effect. A notable exception are introverts - like me - whom I call "socially accessible" introverts. We have been trained well to smile and nod, which can place a burden on our processing efforts.

Asking others for input puts you in the driver's seat, and may feel less awkward than having to watch yourself on video.

When an introvert cares about someone, she also wants contact, not so much to keep up with the events of the other person's life, but to keep up with what's inside: the evolution of ideas, values, thoughts, and feelings.

An extrovert is more likely to share immediate reactions and process information through conversation.

Introverts keep their best stuff inside—that is, until it is ready. And this drives extroverts crazy! The explanation for the introvert’s behavior—and there must be an explanation for this behavior, say the extroverts—is that he or she is antisocial, out of touch, or simply a snob.

As an introvert, you can be your own best friend or your worst enemy. The good news is we generally like our own company, a quality that extroverts often envy. We find comfort in solitude and know how to soothe ourselves.
