I think that the idea of being introverted matches very well with the concept of social interaction as requiring self-regulation. In my experiences adjusting to the college environment, one of the hardest things to accept was the idea that I would have to see and interact with people every day, no matter how I felt. As a homeschooled student, I could easily limit my social interaction in high school, if I didn't feel up to people. I didn't often; I had friends and eventually took classes at the public school where I had to come every day. But social interactions still take work for me, and I still have days where I would just rather not talk to anyone.
