I always score like 10 on that test, which is on the low end.
I can be self-absorbed with my thoughts/feelings, but it's not in a "I'm so great" kind of way. I actually have more insecurities than I express. I may have a slight elitist attitude when it comes to taste, which is a very 4 thing, as it's hiding an insecurity over the true self. I identify with external things to create an image, because deep down I fear I have no personality, or not a very interesting one. However, I don't feel supriority in abilities, worth, etc; I may actually feel inferior.
I am definitely not a jealous person; 4 envy is not about begrudging others what they have, but also wanting similar success/happiness for yourself. It's a "grass is greener" attitude, where you fail to see everyone else has problems & failures of equal magnitude to yours. I can relate a little to that, but it's not what I would call my main emotional motivation by a long shot. I too easily empathize with other people's plights; but that is a sign of a healthy 4, which is encouraging for me to see in myself.
Anyhow, the enneagram descriptions which match each type to a "sin" are a bit too kitschy for my taste. The ones which discuss the 4 need for unique identity and separating yourself from others to define yourself in relation to the group (and therefore have a unique identity), etc, are things I relate to more. There's a need to be significant in some way (making your mark on the world) because you feel insignificant.
