Earlier quoted context omitted.
As a fellow introvert, I would recommend that you see it as taking medication. Or getting exercise. You don't do it because you like it. You do it because if you don't, then you'll be worse off years later.
You say this as if introversion is something to be "cured." It's like telling a gay man that he just needs to try dating more women. There's nothing wrong with being an introvert. It's not really a choice in the first place.
Not at all what I'm saying. You don't get cured by exercise either. You're never "done" exercising. It's just a thing you do, in order to have a long term better life.
I don't like talking to strangers. It still tastes like medicine. I have no expectation that I'll ever like it. But I still have to take my medicine, or I'll be worse off long term.
And like being sore if you've not exercised in a while, the aversion to being social is stronger after taking a "solitude vacation". But you can't not do it.
So yeah, you completely misunderstood.
