Think we have been forgetting the necessity of relationships in a post-internet society. It can be a good thing to be intentional about relationships. The benefits don't only apply to introverts, it can also be important for extroverts to cut off harmful people from their lives and deepen connections with those they need most.
Plus one for intentional relationships. I've become much more careful about who I form bonds with as I've grown older, and I've left a handful of long-term friendships behind when I realize I didn't want those people in my life. I'm not an extrovert, but I do make friends easily and I learned the hard way that if you just make friends with everyone who comes your way, you'll end up with some bad friends.
Appreciate the note on making friends - I’m also not exactly an extrovert and I also make friends easily. I wish I would have known this sooner that it’s not as difficult to make lasting friendships as it may seem.
