After taking the Enneagram quiz my result number was a nine. Which says that I am calm, laid-back and optimistic. I agree with the number I received mainly because I believe that those three traits listed are the three main parts of my overall personality.
All my life I have been quite laid back and calm about most situations, for example; I never really sweat the small stuff that seems to get all the other people worked up and lose sleep over. Also, I tend to take the most favorable view on the conditions presented to me and expect the most favorable outcome, therefore I would also have to agree that at least part of my personality is optimistic.
