Everyone is really different when it comes to personality (hence the graph at the top). You can be introverted, extroverted, or right in the middle, which is known as "ambiverted." Personality plays a huge role in human nature as it shapes our experiences and is the deciding factor in how we act towards the social stimulus.

A misleading stereotype is that all introverts are shut-ins. That's not entirely true, we do enjoy interaction, but in limited doses. For example at a party, an extrovert may gain more energy from social interaction as they spend more and more time there. On the other hand, an introvert will engage in social interaction but will become more tired the more they engage. That's not to say that extroverts don't get tired being at a social event, just that the source of fatigue for introverts is different. Additionally from what I've experienced, and others can back me up on this, small talk is horrible. Arguably, small talk drains us faster than an in-depth conversation. I'd much rather have a short, deep conversation than making small talk for hours. Another thing, the more people you add to the conversation, the quieter we'll tend to be.

As Stephen Hawking once said, "Quiet people have the loudest minds," which is funny because we don't really talk a lot, but it's an entirely true statement because we think a lot. Sometimes the noise in our minds can be deafening, but by secluding ourselves in thought we can become more self-aware and be more focused.

There's nothing wrong with being introverted. Introversion and extraversion are just two different personalities that people can have and it doesn't mean that anyone is better than the other. It's just nice to be able to understand different people's perspectives on things, especially social stimulus.

Introversion and extraversion are just one part of the four (or five) parts that make up your whole personality. Curious about what your personality may be? I recommend taking the personality test by 16personalities to get to know yourself on a deeper level.
