I've read some posts so far on what seems to be a popular topic - ISTJ dating. My impression is that this can be a particular challenge/adventure for this type of personality. Personally, I find this area of life to be the most complicated and I'm not sure why. Overall, I think other personality types must view the ISTJ as boring or robotic.
So, I spend a lot of time looking at how an ISTJ (myself) handles things and wonder if I'm out of lockstep with the rest of the world. I think that I spend a LOT of time overanalyzing, but I find this way of thinking useful since it helps me to avoid problems/mistakes (although, I don't stop until smoke is coming out of my ears, unfortunately.)
As an ISTJ, what type of personality do you find easiest to get along with? I find that I spend most of my time alone when family's not around. Not sure how healthy that is.
