2w1, 9w1, 5w6, and I'm an INTJ. 
I tend to try to act like I'm extroverted in my endless campaign to make a difference and be noticed, but it's pretty tiring. Unlike many INTJ's I have a very positive view of the world and want to help people live to their fullest potential.  
And yes, I know I doesn't sound very INTJ-ish at first glance, but believe me, the description fits me. Don't know how it can work? Nor do I. It just does. 
And also I contradict myself all the time >.< (Head vs. Heart i suppose)
