I am not seeking a conflict here, please note that -- but I don't think you should limit that phenomena to introverts.

I am a pretty outgoing and easy-to-make-friends-with person but I still hate working in offices and 6 or so years ago I fought tooth and nail to achieve it. I succeeded, at the cost of a relationship, very old animal friends, most of my "circle" and quite a bit of few other sacrifices.

My point here is that there are other things to have in mind when choosing between on-site and remote: I personally hate commuting. Even if it's 20 minutes from my door to the office, I still hate them. That's a time nobody pays me for, and a time during which I can't be with my loved one.

Add to this that we all know that no work day is like any other; there are days when you're worth $1 and there are days when you're worth $20,000.

Outgoing, extroverted, expressive, call it what you want -- but I want to work on my own terms. And I am times more productive ever since I work remote. (And yes I am in a very happy relationship.)
