I fount out today that I'm currently an ESTJ, which means that I'm an Extrovert, Sensor, Thinker, and Judger. In a nutshell, this means that I like to take charge, I live in a world of facts–I require facts to make my decisions. I can see a lot of these things to be true, there is a lot more to it of course here------->http://www.personalitypage.com/html/ESTJ.html
I just think that it's interesting to understand what kind of person you are, that way it makes life a little bit easier to live–knowing where you stand on certain things and the process used to get to a conclusion. Anyway, take a look at this website for the "Jung Test"
