Is there such a thing as being both introverts and extroverts?

Quote:
The actual astrology sign Scorpio is not typically described as shy or introverted. They are not Scorpio traits, it's just that Scorpio has a Yin polarity as opposed to Yang. I use Yin and Yang to describe the polarities because there's no confusion in thinking that one is better than the other. You might have heard people describe this as Positive and Negative, Masculine and Feminine, and the one you likely saw was Extroverted and Introverted. This leads to two misconceptions. 

 The first misconception is that everyone born in Yin/Feminine/Negative polarity signs are introverted people, but it's not the people in the signs that are introverted, it's the sign itself that has introverted energy. Most people are a mixture of Yin and Yang energy signs in their birth charts, but others lean more towards one side or the other. However, even if all you signs are Yin or "introverted" signs, it doesn't mean you're an introvert and that is because "introvert" is just a confusing word used to describe the polar energy of a sign and does not mean the same thing as when someone refers to themselves as an introvert. 

The second, and more important, misconception is what introverted actually means. In people, introversion and extroversion are used to describe where a person gets their energy from. Extroversion means that you get your energy and happiness from the world outside of you and the people in it. Many or even most extroverts make friends easily and are energized from loud and exciting environments, and are stereotyped as the partier or popular type, but that is not what extroverted means nor is it accurate. Introverted means you get your energy from within yourself, activities such as reading, writing, painting or even just learning new things give are appealing to most introverts. Introverts are comfortable being alone and feel better through means of self soothing. Introverted does not mean shy, and this is where you get two types of people often forgotten about but surprisingly common, the shy extrovert and the outgoing introvert. Shyness has a lot to do with confidence, something that introversion and extroversion have nothing to do with. The shy extrovert likes being around people and has difficulty being alone or in a quiet room, but doesn't contribute much to the surroundings in return. They might be quiet but the important thing is that they're choosing to be people in a busy environment rather than alone in their room, it doesn't matter if they're talking or being sociable. The outgoing introvert prefers solitude but is confident about their interests and opinions. Because they don't get their energy simply from people, they're actually very interesting, and although they get their energy from themselves, it doesn't mean that they don't project energy elsewhere. Introverts love having conversations actually about something, they don't talk just to talk, so almost everything they say is really entertaining, and if they're confident about their views, they'll do it often and to anyone who'll listen. These are the types to be the life of the party, get a large group of people following them around, and then disappear before the parties over because they'd rather be with just a few of their good friends, which automatically seems cooler than the party. You know the type, the people who everyone seems to need but doesn't seem to need anyone else? That's the outgoing introvert. 

The Scorpios you know might still be truly extroverted, but it's unrelated to how shy they are, and they might actually be introverted. Not all the Yin signs are introverted people and not all the Yang signs are extroverted people, but these are commonly misused terms as well.

This has bugs me for a long time. The person who wrote above was answering the question about what is the difference between extroverts and introverts? Some people misunderstood introverts as being shy. I don't agree with that because I am an introverts for sure but I've never felt like I'm a shy person, well, most of the time. So this definitely clears up my confusion.
