I am a textbook ISTP (the Mechanic).
Its a fairly rare personality type. I haven't read through the entire thread so I am not sure who else on here is one.
This describes me almost perfectly:
https://www.personalitypage.com/ISTP.html I am definitely good logical analysis and technical skill (work in IT), I am great in a crisis, have a hard time expressing my feelings, not much of a rule follower, an endurance athlete and big into fairly extreme sports, never had a "gut feeling" about anything, I make few judgments based on personal values, not much for laying around and always needing to be up doing something.
The Strengths and Weakness Section for ISTPs describes me well:
ISTP Strengths
Good listeners
Usually self-confident
Generally optimistic and fun to be with
Practical and realistic, they handle daily concerns
Are not threatened by conflict or criticism
Able to leave a relationship with relative ease once it is over
Able to administer punishment, although they're not interested in doing so
Likely to respect other's needs for space and privacy
ISTP Weaknesses
Living entirely in the present
Not naturally good at expressing feelings and emotions
Not tuned in to what others are feeling, they may be insensitive at times
Tendency to be overly private and hold back part of themselves
Need a lot of personal space, which they don't like to have invaded
They thrive on action and excitement, and may stir things up to create it
