I may as well respond to the questions to get the ball rolling.
What is your neglected instinct?
Sp
How do you see this play out in your life? What do you neglect, miss out on, or fail to do because of it?
In a lot of different ways, honesty. I tend to be really bad about sustinence/provision/safety related things. I literally forget to eat if I'm not careful about it-- I love food, and cooking, it just doesn't occur to me until I'm famished sometimes. "Foolhardy" is the best word I can find to describe the main issue with being Sp-last, in that I just don't tend to register (or take to heart?) risk very often. This reflects in the way I drive, financial matters, even things like having window blinds open, being very open with my feelings/thoughts or forgetting to remove my pocket knife from my keys before going to the airport.
I experience being Sp-last as somewhat being fly-by-the-seat-of-my-pants, because of that lack of security awareness-- in some ways, I actually think
this is one of the reasons some people see me as INFP, instead of INFJ, because I'm much less of a "planner". Things I miss out on, or neglect: I definitely get sun burned, rained on and
almost run out of gas more frequently than other people. I've probably gotten hurt more (emotionally and physically), but most of the time the risks I take do not actually end in catastrophe. If I'm honest, it's probably by a slim margin sometimes though.
*One last note about the financial thing. It isn't really about spending foolishly, but more like forgetting that money/material things are a thing (or not seeing it as important) in
all ways-- this can be good and/or bad since I neglect to give it attention. I actually think the most money/material-conscious (for better and for worse) people I know are Sp-first.
How might this cause issues and negatively affect relationships with people in your life?
The non-relational stuff I already addressed above. Relationally, I've actually had a lot of (undesired) exposure to Sp because both my Mom and Dad are Sp-first. It's a good thing though, because it's helped me to learn how to respect people's Sp needs, even if I think they are silly. Examples are giving them space and a pre-determined span of time to
move away from conflict, to process and feel secure before we resolve the conflict. For most of my life, I didn't allow this and saw their departure as avoidance and refusal to
engage with me. I still do that sometimes, where I just continue to move
towards, and unintentionally make them feel antagonized.
Being Sp-last also makes all of your loved ones concerned for your well being in general-- or maybe that's just because many of them are
not Sp-last.

The inverse is also a relational issue: my loved ones being a lot more prone to worry, fear and hyper-planning, which I tend to question.
If you've tried to be more attentive to your last instinct, do you think it has helped you to grow?
Heck, yes. When I was totally unaware of this blind spot, I think I actually was sort of in danger sometimes. I did a lot of stupid (rash) things. At least now being aware of it, I can usually stop in the moment, weigh the choice I'm making and then go from there.
