I've been trying to work out how I could possibly be as anti-social as I am. I was talking to an INTP guy I stumbled into in the city and we talked for half an hour or so, and we agreed that I'm more of a hermit than he is... if that's even possible lol. I'm an extravert and an enneagram 7... but also Sx/Sp (possibly the other way round).
I can never find enough to stimulate my mind, it feels like I have to be lucky to stumble upon anything that can satiate my boredom, because it has to be a big enough discovery for it to induce growth, yet short enough to hold my attention span. I get a lot of stimulation from my family at home, I have two brothers (ESFP Sx/Sp and ESTP Sp/Sx) who I hang out with whenever I'm at home, so I'm never actually alone, and I don't need to really go outside of the house to seek company... which may be a different story when I move out.
add: Just read the description again, and it seems that what I've described is exactly what Sx is, although it's not the people seeking version, it's the stimulation seeking version. Sx fits me perfectly, and there are a lot of other ENXPs here that are also Sx/Sp types.
