Nafcillin- Have you ever taken a personality test?
I think you're an INTp (NiTeFiSe). Ni would be your primary, Te your secondary, Fi your tertiary, and Se your last and least-developed function. The application of "what works and what doesn't" suggests that you use introverted intuition to apply extroverted thinking. Ni builds the "pattern" and Te applies it. Fi may manifest as depression or social ineptness, if your work environment is too hostile towards you. An uneasiness and dislike for an inconsistent work environment could be your least developed function coming through and struggling- Se.
My close relative is INTp, and she has social anxiety and anger issues, too... but she's successful. 🙂
Ni makes for a hard life. People don't understand my train of thought, a rock hits my stomach every time management comes in because I *know* they'll find something wrong, and coupon cards have gotten the best of me- because they *always* suck. I'm INFp (NiFeTiSe), and it only takes 2 or 3 times of something happening for me to see the "pattern".
Fe saves my ***. If it weren't for Fe, then I would be rude and condescending towards everyone, because I wouldn't care to interact with people.
Anyway... As an INTp pharmacist, I would go into academia or become an entrepreneur, both of which would utilize Ni and Te well. And Fi would be less of an object, I would think, since those fields require and value functions like Ni and Te.
