Okay, I retook the MBTI test, and got some results which actually make more sense to me than ESTJ. I thought a lot more about the questions I was answering; I actually looked at my life and said "do I do this?", and with the ones with which I would've once straight off "agreed", I actually stopped and thought about them, and could change to "disagree" very easily. The results resonate with a different MBTI test I've taken in the past. I got INTJ.
(I also got 8w9 at 76% for 8, 56% for 9 (and 26% for 7), followed closely by 1 at 63% and 3 at 56%.)
