When I start thinking about this mindset I just want to curl up into the fetal position. I get that it's just how some people work and it seems fine for them, but applying it personally is painful. I shut the world of sensation *out* as a kid and used my mindset to have a measure of control over it - that's part of why I developed with Ni dominance.
Due to the focus, I'd put an auxiliary Feeling to it. So, have you considered ISFJ or ESFP?
