Do you think overall that introverts or extroverts have an easier life?

Honestly, I expect neither. The world is becoming impersonal, superficial with social media, and while an extrovert might excel in that, forgive my observation, as I'm not trying to say extroverts don't have needs in intimacy, I think they do and maybe how I am basing my opinion somewhat, that an introvert that might feel closed off from this world, often, knows how to create friendships that hold meaning to them? Almost all of us need companionship, friendship of a kind, some don't know how to find it, and some don't know how to create it when they find the possibility?

Extrovert probably have it easier,

But I could be biased because I'm a hardcore introvert, and I always try to do everything myself,

Whereas I imagine extroverts would find it easier to make connections with people who could help them

as an introvert, I assume mine is simpler, but extroverts have it easier in many ways.
