Yea, there are definitely more important/interesting subjects I could sink my time into the study of (within typology as well)........
At this point, I've milked all the personal insight out of socionics I can possibly gain. It seems that every form of typology becomes very subjective and then there's a point where you just don't need it anymore because you've created your own workable typology system. I don't really need socionics.
I think it becomes a religion for some people and they need it, along with their interpretation of it. Makes sense because it improves their lives, and they don't want to let go. They need a belief system to cling to...... So trying to convince them of other-than what they believe is probably non-productive and could be codependent. (Discussion is one thing; a need to convince is another).
