I got ISFJ.

ISFJ, interesting, described as "nurturer" I suppose that means you like to take care of your responsibilities more or something? You like to take duty, may be?
I got ISFJ as well. This It's funny because the description here is pretty much word for word the way I described my fursona for the first RP I was in >.<
Retaking for the first time since about a year ago, ISFP. Interesting.
ISFP "the artist" and "the action taker", quite similar to nurturer as the "doer", you enjoy more the doing than the result of an action (although I'm sure you appreciate the result as it reflects what you sense a lot as a sensing individual when you are expressing yourself), which is slightly different to an INFP, who is a bit more result oriented "a visionary" as it were, a "concept maker" so the expression of an action comes more pre-motivated, quite similar though. I can see how your personality can change slightly over time by situation changes, but the overall of yourself will seem to stay the same, hence people can get stuck in their ways thanks to certain elements of permanent psychology. I don't think I've ever changed my personality, though (proper test review evaluation always results the same), not like I haven't noticed changes in time among others. Interesting indeed.
