Hi! :hi:
Things are not always "black and white."
I'm an ESTP 7w8, and I am horrifically realistic AND driven, but also ridiculously entertaining.
This just seems at odds to me.
What is your basic fear in life?
That is a central Enneagram question.
Don't think too much, just type it out and go from there.
7's are adventures, yes, but 7w6's are more
"accomodating" and
"pleasant" and
"easy going" than their 7w8 cousins.
7w8's are DRIVEN in spite of being playful and adventurous.
A dear, dear, dear friend of mine is a 7w6.
Whenever she and I talk on the phone or in person it's like I'm talking to part of my soul.
It's amazing.
But, it's the
"nice" part of my soul that she mirros.
She is a creature of joy.
She can walk into a room and instantly promote peace and harmony and goodwill from all toward all.
I can do that too, but I'm also just as prone to kick ass and take names.
I am a creature of PURPOSE.
I champion my own free will at all costs, yes, but I also have a master plan, no matter what I'm doing.
I'm PURPOSE driven, and will do whatever is needed to accomplish my objectives, to live the adventures in my heart.
I tried to help!

Another example.
One of my best male friends is an ENTP 8w7.
Witnessing us in the same room is horrifying.
We push our agendas through (on a unified front at all times, of course) and make a spectacle of whatever in the course of things, and then leave the masses to clean up the mess while we wander off in search of more clues.
Compared to him, I'm a bit soft around the edges, but he is a bit inflexible even when unecessary, because his primary fear is that of being CONTROLLED, whereas mine is of being UNFULFILLED.
Good luck trying to control me, I move too fast!

Those type of differences might be useful to you, at least I hope so.
If I had to guess, I'd say you are NOT 7w8, but I'll not wager on what your exact Enneagram type is as at this point.
Let's see how your thread progresses.
Maybe [MENTION=6164]Riva[/MENTION] can chime in on this?
He's damn good at this stuff.
