I don't consider the root cause to be extroversion at all. That's one particular reason why I don't like working at home, but I could (and did) just rent office space to deal with that. The problem is that I'm afraid of succeeding -- so, for example, when I rented office space, I didn't go all the time. Or when my company offered to move me from the UK to Austin to be around them all the time, I said no.

2) is correct. I would have felt like I needed to do everything to the best standard because the people I was working for were around around me. I'd feel a much more personal connection with them, and I wouldn't want to let them down, so I'd get my work done, and do it well. And I'd be less afraid about speaking up, or mentioning problems, in person. It's also a lot easier to demarcate between work and not-work time when you're working at an office.
