It has to be S for me. That sensing side is the one thing I can't do. To be able to pick up instruments and play them, dive into the action of life head on, not go drifting out of the moment, see all the details and colours perfectly.
If I had to do a full type change, ISTP.
If it was long term and not just for a month, you couldn't do anything to get me to change type.
Freude, schöner Götterfunken Tochter aus Elysium, Wir betreten feuertrunken, Himmlische, dein Heiligtum! Deine Zauber binden wieder Was die Mode streng geteilt; Alle Menschen werden Brüder, Wo dein sanfter Flügel weilt.
So if you are an I, you'd become an E, If you prefer F, you'd rely more on T............yeah you get it, a swap.
The thing is, it's a trial basis. so, let's say, maybe after a month, you'd switch back to your original preference. A month is probably a good enough amount of time to experience fully whatever letter you trade in.
Oh yeah, you can trade in any combination as well, so if you want to trade in you IS for EN, that's perfectly fine.
So, which would you trade in? Would it be one? Two?, maybe all 4?
I think I'd go with ENTJ, assuming I would still have the same goals upon switching. Being an ENTJ for a month or two would kickstart my plans and get me a lot further than I can get with my passive, sensitive, cautious IF nature... I'd probably successfully do things that would scare the heck out of me right now, get over some major humps and make myself figure out how to do a lot of things. That progress would probably benefit me for a long time after I switched back.
