Si-doms are the easiest.
As a 18-year-old, most people I'm friends with are Se-doms/aux. It's very easy to find them.
Also, I instantly feel a "connection" when I meet iNtuitive types, most likely when they're Ni-doms/aux.
I guess the worst to type are ENxPs. Firstly because they sometimes come off as Sensors, from my experience, and sometimes, as Introverts. It's tough.
When typing my ENTP boyfriend, I first thought he was an ISTP, then an INTP and now we finally settled for ENTP.
[With poetry, one] is capable of going beyond the limitations of coherent logic, and conveying the deep complexity and truth of the impalpable connections and hidden phenomena of life. Andrei Tarkovsky, Sculpting in Time
