Sometimes I think that I'm doing what I do at the cost of consistent personal relations, the sort that some individuals around me have: an intimate, inner circle who are the world. I do have something similar, I guess, but it's more like a large circle of sporadic close contact.
I'm not sure I like that.
Perhaps this is why I don't think I can sustain my current lifestyle -- but once I shed it, there is always the possibility that I will "settle" only to realize tremendous dissatisfaction.
(by the way, emphasizing "do" over "think" makes it easy not to deal with these issues, at least, in the short term. ;) )
