Free Meyers Briggs Indicator Test (so fucking crazy and accurate)
It's CRAZY how accurate this is...I think it can be instrumental to "figuring out" your life, and more importantly, understanding and improving your approach to jiu jitsu, try it out!
I am an INFP, what are you (if you do the test, it will explain what all the weird letters mean and what it says about the way you see the world :)?
I think it would be really interesting to see if there is a personality type that is more successful at jiu jitsu...my hunch is that there is not, b/c there are so many different approaches to bjj.
