I am self preservation as hell. lol. I'm constantly noticing how comfortable a chair is, how good the a cup of tea tastes, or how uncomfortble my dorm is. when I'm in a dangerous situation, my first instinct is "hmm, how do I not die in this situation?" (I had an SO/SX ESFP friend growing up who didn't care at all about his own safety. he would jump off stuff and almost kill himself and not even seem to care or learn from his mistakes).
On that note, knowing this helps me make more sense of my entrepreneural tendencies. SP doms are like..."um this isn't good enough, I'm gonna go get something better" when you take this combined with being 4w3 and your our refined tastes for everything, you pretty much have to be an entrepreneur or a singer if you're SP/SX 4w3 (and I'm both ^v^ )
