Yeah okay well I can go with the first part, but no, there's really not much 9 in me at all, but still very much of 5.
It could be that I'm a sorta exceptional case in that I did have a very violent, traumatic event that sorta ruptured my life from early 20's onwards kind of totally asunder from my life previous to that, so that I not only developed in a direction that was very artificial, with a sort of 'forced' personality of introverted behaviour, leading to my seeking solace and to make sense of the deep shit i was in through the acquisition of knowledge and very 5 type behaviour. But then when I was sorta liberated from that in a completely unforeseeable way, my whole personality was able to take off in a totally different direction as my actual authentic extraversion made itself known.
Hm... my first objection to the official Enneagram system was that I felt I should be 8w5 haha... but up to my early 20's I really was a very stereotypical 5, whilst as I say, now most people say (including the pro Enneagram dude I know in RL) that I'm split down the middle between 7 and 8.
