A wonderful friend once got me into the Enneagram personality test. There's every a big book about it.
I feel like it's much better than that rubbish Myers-Briggs test.
You can read about the Enneagram on the wikipedia page, I just here wanted to save an image of the nine types, and my own results ( 7, 4, 1 ) (enthusiast, individualist, reformer)... although I only did a very quick online test, so I'm not sure how accurate!
