I put this link up before somewhere. It's a personality test (and not the crappy sort). Most of us being young, it helps with the sort of career you should be looking at following, and why you do the things you do.

You don't have to answer every question on the test, but its not very accurate if you leave too many out.
More in-depth information on your personality type is here: http://www.geocities.com/lifexplore/
Look under recources and select type profiles.
Information career-wise, go here: http://www.personalitypage.com/careers.html
post your personality type up here, so we know what you got. Myers-briggs also gives you the percent of population in the types.
(I was the INTP, the Architect or Wizard. Like Socrates and Newton, and Einstein... and aparantly Meryl Streep... )
I'm INTJ too.. although I'm slightly expressed in everything but intuition, where I'm moderately expressed..
