I don't believe that introversion is like sedentary lifestyle, which can be cured through exercise. I have taught myself to socialize, and people tell me I am good at it. But it has never stopped being draining. I just do it because I know it helps me socially and professionally. Discomfort hasn't really been a factor since my mid-thirtiesbut it is still as exhausting. Unlike in my teens I get invited to parties, but I still go home early.
Exactly, it's not that there's an initial hump of energy loss that you get over and it gets easier, it's the same even with those you've known a long time. However, I've come to realise I spend a lot of time complaining about social interaction draining me, but almost none allowing myself the time to have social interaction and recover afterward.
