Are you familiar with the enneagram at all? I'm a 6w5 so I doubt myself constantly and look to others to affirm things. I assume, with the new info I am learning about extroverts, that 6's cannot be introverts. Having a 5 wing usually makes a 6 more introverted and less social and more ambiverted.
I tend to think out loud and need a sounding board to figure out what's going on in my head. I would
like to be more independent and I am more so now (since learning about the enneagram), than I have ever been, but the bottom line is, I tend to look outward for support and re-assurance. This sounds like an extrovert to me...
Btw, Orange, thanks for your help. Seriously. You seem to have a firm grasp on these differences and I find your communication style helpful and invaluable
