I quit using terms like "real job" and "real world" a long time ago (back when I was working as a deckhand on a ship). I don't like that it implies that you are doing something less- that other people are more legitimate because they are on the beaten path. Now I use the term "regular job" and "regular world". On another note, some people thrive in the solo-work arrangement. My creativity has soared since I quit having senseless meetings, or bureaucratic red tape to get through. Good that you recognized that you don't naturally build social networks- As my business has grown it forced me out to meet so many people that now I have reserved entire days to be back in my private office working alone- hoping I can tap into the creativity that comes from solitude.
