I become obsessed and enthralled with the work itself, sometimes to the point of wanting to work 12-16 hour days to solve deeper problems that are bothersome. Working short days has never been an issue for me. This is exactly what I mean by projection. You would want to leave early if you felt isolated. But I enjoy it and want to stay longer.
>I worked remotely for a couple of years and now realized how much more i enjoy work when i have other developers around, otherwise i would lead a pretty lonely live.
This is not "fairly introverted." What you are describing is a textbook example of "fairly extroverted." You enjoy working around others and begin to feel lonely otherwise. I generally don't, in either case.
