So i am gonna copy tom, cause i just read his (http://tomcampbell77.blogspot.com) and he talks about personality tests. so there is one where they give you four letters (introvert or extrovert, sensing or intuitive (n), feeling or thinking, and judging or perceiving). Mine is ISFJ. I read the description and i was like - whoa! that is me! but other parts i was like - whoa or not. But at most times i was like - ok is this person stalking me????? so yeah - take the test - http://www.humanmetrics.com/cgi-win/JTypes2.asp
or just read about the types
http://www.personalitypage.com
in case you were wondering here is what mine said::
Quiet, kind, and conscientious. Can be depended on to follow through. Usually puts the needs of others above their own needs. Stable and practical, they value security and traditions. Well-developed sense of space and function. Rich inner world of observations about people. Extremely perceptive of other's feelings. Interested in serving others.

or here is the long version -
just kidding, its freaking long. go read it yourself if you are so interested. :)
