The second is learning how to communicate with your counterpart. If you're an Extrovert, you're probably quite social. Being around other people energizes you and you find being alone draining. You probably initiate conversation, say what's on your mind, think out loud and speak first, think later. You may find yourself planning your response while the other person is still talking.
Introverts are almost the opposite.
You get your energy from within and often find social events tiring. Most likely you are a great listener, do your best thinking alone, pause to reflect before speaking and choose your words carefully. You may often find yourself leaving a meeting without saying what's on your mind. Although these descriptions are brief, it's easy to see these are two different communication styles. By not only recognizing the differences, but respecting them as well.
