Enneagram

I read an interesting e-book about different personality types via this post. There are 9 different personality types described by a kind of star inscribed in a circle called the enneagram. The idea is that the different personality types complement each other. According to a short online test (there is a longer test for $10), I am a tie between Type 1 (the achiever) and Type 6 (the loyalist). The e-book by Mark McGuinness suggests that we become entrenched in our types and we should try to incorporate the strengths of other types into other lives. For example, a Type 1 achiever should stop to enjoy the moment. The enneagram seems like a nice way to methodically examine yourself and compensate for the weaknesses of your personalities.
