An analogy is a rock skipping across a pond - touching many parts of the lake, but none too deeply. Extraverts tend to think out loud. If you are an Introvert , you prefer your energy to flow inwards, into ideas and concepts and your attention is naturally drawn to the internal world of understanding. Because you focus inwards, you tend to become more thoughtful and your interests are deeper. An analogy is a rock tossed into a pond - hitting once and sinking deeply.
Introverts tend to keep their thoughts to themselves.
We are talking about preferences - NOT limitations. Just because you are right-handed doesn't mean you can't use your left hand. Understanding your type should lead to better decisions, not restricted choices. Never let anyone suggest that because you are such and such a type, you would not be good at something. Bill's an extravert and Betty's an introvert.
