Everyone knows that there are people who are extroverts and those who are introverts. Extroverts are social butterflies who thrive off of being social. Introverts are the complete opposites (mostly) and there is nothing wrong with that.
Just because someone finds socializing exhausting does not mean that they hate people or are not fun to be around. Many introverts have great friends but may just not enjoy parties or meeting new people and that is okay. You cannot really control whether you are an extrovert or an introvert either. Introverts cannot help the fact that interacting with other people for long periods of time exhausts them and takes a lot out of them. Extroverts cannot help that they thrive on socializing and may find it challenging to be alone.
Many introverts do not mind being by themselves sometimes. In fact, they probably love their time alone. It is their chance to recharge and reenergize. This can be one of the best benefits to being an introvert. Odds are, introverts are also pretty calm, cool, and collected which can pay off in the job market and when forming long-lasting relationships. Since introverts do not rely on others to stimulate them, they are most likely extremely independent and value the relationships they have a lot as well.
Introverts are "in their heads" usually more than extroverts are which means they can be superb listeners, great at self-reflection, very creative, good problem solvers, excellent at making rational decisions, and extremely independent. The important thing to remember is that just because American society seems to value the extrovert personality type more, does not mean that it is at all superior. Half of people are extroverts and half are introverts. It is time to stop underestimating and undervaluing introverts once and for all.
