I don't know how much stock I put into these things either, because I don't know enough about it to know the strengths and weaknesses of it. I don't know much about psychology so I don't really have an informed enough opinion.
Plus, I don't know what is THE definitive version of the test. I've just taken this free one online:

But, I've taken this one version of the test a few times, since I got curious about it as I started seeing more and more people talk about Myers-Briggs types.
One thing I feel is that a lot of the questions were hard for me to answer, in that my answer could change depending on the situation. For example, I'm introverted most of the time. But if I'm at a party among friends, I can be very extraverted (especially after a few brewski's, lol). But it's not just that. My answers could change based on my moods too. I feel like the questions are too general to describe how I am and how I think and feel in every situation all the time.
I think I got INFJ (Advocate) once, and INFP (Mediator) twice.
These are the results from my most recent test, just now:
