Discovering Your Personality Type

I've read a lot on the Enneagram Institute website, and other than different type descriptions, there's nothing new here. You can take a different (and in my opinion, more accurate) test online as well. The history/origin of the Enneagram, or more in-depth psychology observations would better lend itself to book format, but this is not it.

I much prefer (and highly recommend) The Road Back to You by Ian Cron and Suzanne Stabile.
