Before we talked as much about introversion and extroversion, people felt more obligated to do certain social events that they can more easily reject nowadays. That does mean it was uncomfortable and they had to push through friction because it's draining for introverts to do social events but being there also helped with making group of friends and staving loneliness. I do think this change in mores is one of the factors that contributes to the so called loneliness epidemics nowadays.
I hate exercise. Like I really really really hate it.
Should I just accept this and live a life without it?
I don’t think it’s such a stretch to say that socialisation is similar.
That is entirely up to you. It's your personal life and your time. No one has the right to say what you should or must do with your time.
Just like socialization, it's up to you on how much you do or don't do. Pretending everyone needs to because you like to is stupid.
Socialization is exhausting, I have to do enough of that working. I am not going to on my personal time. I really don't care what other people think of it, or what justification they use to try and make it some sort of requirement, or how much finger waving they're going to do.
