I and T are clear due to belief of not being able to identify with others.
Chart-the-Course focus on future, directive-reactive style is also clear...As is the NT desire for competence (or could be SP skill acquisition).
So INTJ, ISTP, or INTP with some Chart-the-Course interaction style.
Style of observation and analysis indicates a more Ni style than Ti style, and a preference for abstraction language.
So INTJ with a slight chance of IxTP.
In my perception, for your particular case, the more N you are, the more likely you are a J, and vice versa.
