I took the online versions of this personality test (I don't know how to take an 'official' one), just because I keep hearing about it. All three tests I took (one, two, three) said that I am INFJ with the J being only slightly ahead by 10-21%.

You guys seem to have a lot of knowledge about it - what does it mean? What are your types? Whats the point in knowing?

Edit: I looked up some info on it and it reaaaally sounds like me. It seems so accurate.
