I think of things in multifaceted ways, my friend.
Yeah, I don't really question INFP.
I know this wasn't to me, but, just understand, I didn't identify with most the enneagram 6 descriptions either.
Which books do you have?
Are you aware that e6 is considered the most varied of all the types?
As in, within e6, there is a whole lot of variety -- with some types being almost opposites of the others (they share a common core, tho).
(The reason they end up/seem like almost polar opposites is because of how the different subtypes react to that common core)
6s are also one of the two types who tend to have the most difficulty figuring out their e-type (the other being 9s)
Your e-type would most certainly be counterphobic.
There are then two different strains of counterphobic 6s (the third strain/subtype being phobic, which you are not).
I've felt this way for a pretty long time -- never thought e4 or e9 made sense for you, and a lot of your behavior resembles my own.
(Don't think that when I wrote that bit about you, I didn't also see myself in the description)
(And the way you responded to it... straight out of my playbook... as in, to. a.
tee.)
Anyway, parts of 'Personality Types' be Riso & Hudson have some good e6 information.
(Although they do too much switching between phobic and counterphobic types)
(And do so without dilineating them well at all, nor addressing all three subtypes of 6s)
The best places for information on 6s are Naranjo's 'Character and Neurosis' and Armando Molina's 'Our Ways: Values & Character'
The former is, as you probably know (and might already own), the Enneagram Bible, and the latter is, imo, the best book out there.
The former you can get anywhere, including Amazon; the latter you have to order from a
Dutch publisher for ~$50.
