Currently an unarmed private security officer, just because I needed a job. It's a surprisingly good fit; I've kept on doing it from sheer inertia, much longer than any other job I've ever had, even though the pay is crap.
Some of my past jobs, which I don't necessarily recommend for INFPs (given that I no longer have them): dining room attendant, retail cashier, tutor, groundskeeper, university custodian, shipping & receiving clerk, office assistant, proofreader, ISP tech support rep, computer database programmer and high school algebra teacher.
So. Yeah. Seems like most jobs really need an E, S, T and/or J -- or maybe I've just been trying the wrong ones? I didn't know my type even though I took the MBTI several times, because my results were diffuse and changeable, which I now realize is typical of an enneagrammatic 9.
Fortunately, I've become more empathetic, tactful, mundanely communicative and emotionally resilient over the years, actualizing more of my type's potential while minimizing some less-healthy tendencies. I feel pretty good about my chances in taking on a more challenging (and rewarding) job again. Any suggestions for what to try next?
