I quite like this definition of what it means to be introverted vs. extroverted:
An introvert is a person who is drained when being with other people, and is re-energized when being alone by themselves. An extrovert is a person who is drained when being alone, and is re-energized when being with other people.
Or, a little more practical:
After a long week of work, the introvert says: “Finally, I’ll get some time by myself”, while the extrovert will say “Finally, I’ll get to spend time with friends.”
I am an introvert. I need more time alone than I need to spend time with other people. I have known this all my life, but I still struggle to accept it. For some reason I feel that I should spend more time with other people. I should go out more often (especially now that the Corona lock-down is over).
