I cannot deny that figuring out my exact type (it's all subjective anyway) is not the be all end all for me and one of reasons I delayed responding. (Coupled with the fact that my computer died and I didn't have anything to work with other than my phone. Just bought a new computer) I don't say this to be unkind, but I've been in this type of discussion before and they just muddy the water for me. There is not a 100% conclusive way to decide and when I go down that path it just reintroduces confusion. However, I'll just say that when I go down that path I always end up back where I started and end up deciding once again that ISTJ seems to be the closest IMO. For what it's worth my daughter who knows a lot more about MBTI than I do thinks there is a strong possibility that I am an ISTP, but even she is not sure and says that those who are older are much harder to type and that I could very well be an ISTJ.
I've been in and out of rabbit holes (in a manner of speaking) many times when it comes to pinning down my exact personality type. As I've mentioned already age (life experiences) plays a large role in how I present myself today. I am very different than I was in my younger years when I thought I knew so much more than I do now. I've had so many life experiences that have caused me to step back and take a closer look at my values, viewpoints, opinions, choices, etc. I don't like being wrong, don't like needing to apologize (but I do when I know I'm wrong) and that has prompted some of the changes in me as much as anything.
It's really hard to explain in a manner that others would understand, but life experiences have caused me to see things much differently than I use to. Prompted me to approach others and life in general in a different manner than I use to. I am now more focused on trying to control only that which I have true power to impact and control and that is myself. I have found embracing that way of thinking to be quite liberating. I could go on and on, but I won't.
I found this list and pretty much everything on it was true of me when I was younger. Most of it is still true of me today.
