I haven't thought too much about it to be honest. My only motivation for taking the test being that it would be a nice feather in my cap. I know you like to use it as a benchmark for your progress and assure you are getting a rounded education and that seems to be working for you.
My benchmark is to be able to enjoy japanese media without too much effort and to understand whats going on when I visit Japan. It seems the JLPT tests some skills that simply aren't a priority for me at this point, so I'm not as interested in spending much time studying things outside of my immediate goals right now. But who knows how I'll be feeling in 8 months. I'll probably take it if I feel I have a good chance of passing without too much test specific study.
