I love all psychology-type things, and took this personality test today! I thought the results it gave me were really cool, it described my personally to a T, so if you want to know all about what makes me tick, read here and here! Best of all, my fellow "INFJ" personality types include Mother Theresa, Ghandi and Martin Luther king - so if you have any global, social or economic wrongs to right - I'm your gal!!
Try it for yourself - I'd love to hear what personality type you are and if you think it's an accurate description of how you perceive yourselff !!
