What does it mean to you to be extroverted or what kind of benefits do you want to achieve by emulating this trait(s)?
Personally, I really don't like this differentiation between introverts and extroverts because I don't see where I fit in on this scale. Reducing so many hard to define traits like empathy, compassion, charisma, social competence, emotional intelligence, etc. and all kind of personal experiences and habits to a single binary label doesn't make a lot of sense to me.
Are you an introvert if you don't like to be around most people in your current environment but can't stop talking for hours when you're around people that you actually like?
Do you become introvert after an unfortunate series of events, which create serious trust issues and result in you staying at home more often instead of constantly going out like in the past?
Are you an extrovert when you can't be alone because then you will experiences constant FOMO, can't stop yourself from ruminating or need constant approvement from others and socializing whenever you can is your only coping mechanism.
Are you a real extrovert if you get along really good with a lot of strangers on a daily basis as part of your job but prefer to spend most of your free time alone reading, painting etc.?
Sometimes it looks almost like a self-fullfilling-prophecy when someone labels themself this way.
