One book I'll be purchasing soon is "The Wisdom of the Enneagram: The Complete Guide to Psychological and Spiritual Growth for the Nine Personality Types." It's pretty fascinating stuff and gives you a deeper perspective on your personality and your basic fears and desires. Its kinda like the Myers Briggs test but more in depth. I took a basic Enneagram test and I'm Type 4, the Individualist (The Sensitive, Withdrawn Type: Expressive, Dramatic, Self-Absorbed, and Temperamental). When I first read the description I was in awe to how in detail it described some of thought and emotive processes. I'm usually pretty skeptical about personality tests but this was really spot on. Learn more about it here: http://www.enneagraminstitute.com/ Has anyone else ever looked into this?
The test on the website I posted is $10 to take but if you google "free enneagram test" many things'll come up.
This subject is highly interesting to me. I took the test a while ago and scored 5. Cant remember the wing though. Have you tried taking the myers-briggs personality test?
