I am a Myers-Briggs "P" where my long-suffering wife is a "J." So, I'm very comfortable with changing plans on the fly where that drives her crazy because she loves order and certainty.
I found my personality was very useful in the field where changing a plan to adapt to changed circumstances was a useful skill. Heck, it's a useful skill for what I do now.
I hadn’t taken that test before. I’m an ENTJ, according to the test. Some of it may be a bit flawed, though. It only scored me moderate preference for thinking over feeling. While I have empathy, I like to think I do what is right based on reason more than emotion.
Well, no short test gives a perfect personality profile.
