When I first started getting into Enneagram at a shallow level, I thought I was sp (self-preservation). But, it doesn't really capture what I'm really like IRL. I'd noticed for a while doing the online MBTI tests and a couple of personality tests I had to do at work that even though I test as a heavy introvert, I always answer 'wide circle of friends and acquaintances' rather than the usual introvert answer of 'a couple of close friends'. I have no close friends IRL, but there are about 30 or 40 people I could ring and say come over for dinner or lets go out for coffee (which I rarely do, but it's always there as an option and I often have low-grade background guilt that I so rarely do this).
I also became aware sometime last year that perceived rejection from anyone was the one thing that was guaranteed to send me into a rapid severe downward spiral. I've had to work really hard at trying to overcome that, but it still rears its ugly head at times and I tend to need external feedback to snap out of it. Also, looking back, this makes sense of the endless complaints in my blog about being frustrated about lack of depth and connection with various friends but at the same time, holding myself back. That's changed a bit since I moved out and it's been good.
But the main reason why this so/sx rings true is how I am at work. I am a compulsive networker. A couple of years ago at work (before our organisation expanded and restructured a gazillion times), I used to know about 100+ (maybe 200? I can't remember now) people by name. I had a contact in most teams and knew what networks they were tapped into. I was always the go-to person in my team if someone needed a contact in a particular area, and as well as giving them a name, I'd also give a potted bio, including key weaknesses and strengths, how trustworthy/reliable the person was and any important personality clashes that my colleague needed to be aware of when talking to the contact. This was all in my head, never needed to look any of this up or write it down anywhere, except for phone numbers.
For various reasons, I've now lost most of those internal networks. But, thinking about it, it's also because the projects I work on these days are very externally focussed. I still do the compulsive networking and connecting people who need to be connected to progress their work but only outside my organisation, or occasionally within my team.
I find it really easy to pick up the politics internally and externally with the various organisations we interact with - how to influence, what to avoid, how to progress multiple agendas at once by various actions, setting things up now to allow progress a few years down the track for stuff that I can see looming on the horizon etc. This is despite being fairly clueless with interpersonal skills (I've had to work really hard at that in order to be able to convert abstract political knowledge into concrete outcomes). In the past, I was too junior and unconfident to influence things directly, but I always knew who was the key person to have a quiet word to so that whatever needed to happen would happen. Behind the scenes ftw.
