In the world, people are typically seen as extroverted or introverted. You are either super outgoing and love to be around people, or you prefer the serenity of quiet and seclusion. Neither are a bad things to have, and for some, they can be a mixture of both. As humans, we are fickle creatures. We will not always want to be out with friends and be the center of attention. Nor will we always want to spend time alone to be with ourselves.
For myself, I've always been viewed as the outgoing, extroverted type and there's no denying that. In a group of people, I'm typically laughing and having fun with the rest of them. When I'm out with my friends and I am in that extroverted state of mind, I am beyond happy and elated. I both love to talk to people and listen to what they say; though a common misconception is that extroverts like to be the center of attention. Of course, that can be true for some, but for me, sharing personal experiences of my own and hearing the experiences of others are both wonderful things in life. I very rarely enjoy being the center of attention. I would prefer to let others have their time and enjoy those moments with them. Just being around people can also make me feel at ease. I don't always feel the need to fill the silence with mindless chatter, though I do love to talk. Not all extroverts love talking all of the time. We can enjoy the company of others in a peaceful silence while we do work or focus on other tasks. Just being around others can invigorate me.
Yet, on some days, I am exhausted by people. On those days, the thought of having to carry on a conversation with someone for even a minute seems to take all of my effort. I crave the idea of being alone for a short time so I can recuperate from a long day of social interaction. People usually ask if I am alright on these days because I am not the talkative, outgoing person I was a day before. It definitely isn't that I'm not happy; I'm always happy in most cases. On these days, I'm just more happy spending time by myself. I spend a majority of the time by myself doing some self-reflection as a way to recharge from being out and socializing all the time. Being out with people for a long period of time can overstimulate emotions that you get from people, and it is nice to sit back and focus on your own emotions and how you are doing. I often do this when I'm feeling more extroverted.
