Well, since no one seems to be answering my question, I guess I'll just have to give this a go.
In terms of Fun-loving vs. Challenging, I'd be exactly in the middle. I know what my priorities are and I be sure to take care of my necessities, but I wouldn't go so far as to say that I prefer my life to be more complicated than it needs to be, which is the impression that I get from the word "Challenging."
When it comes to inclination... I'm probably more on the independent side, but I enjoy working with others as well... in most situations. Some people can be difficult.
Now I can definitely say I'd be more assertive, but I don't understand how equivocal is on the same spectrum.
Edit: Whoops, forgot. I'm an ISTJ- moderate I, strong everything else. As for Ennegram, I've gotten 1, 3, and 8, and I honestly have no clue what the "w" means or much more about it than the results I've gotten.
Is it that by its indefiniteness it shadows forth the heartless voids and immensities of the universe, and thus stabs us from behind with the thought of annihilation, when beholding the white depths of the milky way?
“I made you take time to look at what I saw and when you took time to really notice my flower, you hung all your associations with flowers on my flower and you write about my flower as if I think and see what you think and see—and I don't.”
