Hm.... there are some things on this post that I have been thinking about...
I don't think that feeler types are necessarily likely to feel more fulfillment if working with people or working towards helping people. I tried my hand at teaching... and counseling.... and it was awfully draining for me. My introvertedness level is VERY high - in the 80s, and sometimes I test out as 100%. Spending all that time with people... even when not directly talking/working with them took a huge toll on me. Overall, i think i spend most of my time helping or understanding family/friends's needs, so that is a job in itself for me. The ENFJs I have known also preferred administrative, organizing work, and less work dealing directly with people.
on the other hand, my dad (an introverted thinker) finds a lot of fulfillment in his career, which focuses on helping others and involves a lot of mentoring, counseling. A lot of it is independent, but still, he is very compassionate and finds fulfillment in this. ironically, he spends more of his time analyzing and theorizing things so I find it amusing that he finds so much fulfillment in helping others. i've been noticing this a lot with my introverted thinker friends that are older, too.
As an INFJ, I don't necessarily want a
career that helps or benefit society in some way.. I've done a lot of volunteer work and working in jobs geared towards helping others, but i realize now that is not my passion or my fit. it is definitely a noble cause, but i am not cut out for it. the talking/being around others constantly is draining. and moreover, it was crushing for me at times because i empathized so much with those communities i was volunteering in and i started becoming really pessimistic about what good could come out of my work. (and i worked in really poor, below the poverty line communities, teaching kids and helping out with families). That said, teaching is still something i do-- i love coming up with teaching plans and new techniques, ideas, projects. I enjoy the occasional teaching here and there (mainly helping my friends who currently teach). my friends who teach have told me that i inspire them and they don't know why i don't pursue this as an occupation.... but hehe, once every so often is good for me now. no moreee!
So in response to the idea of INFJs working in careers that help/benefit people... I would have to disagree with that. I really think it is an individual thing, perhaps even correlated to enneagram type, but not necessarily correlated with type persay.
I agree with what you say about the inner passion though -- and the sense of wholeness.
For INFJs, I believe that something we do for our living has to relate to our ideals, our values, and our ideology. I think that more than other types, we are less likely to think "that's just my job, but this is my life." i think we are more prone to view our job as part of our life, a part of who we are, and a symbol of what we embrace. and we may be prone to spend more time trying to find "what fits" for us. Because our job is the tip of the iceberg that is exposed to all those around us, we tend to attach more significance to it. it has to somehow mesh with our values and our goals, whatever it is. For every individual person, i think this differs, but the main point is that the job we pursue has to be in line with our idealism -- so in a sense, our job is a pragmatic/realistic manifestation of our ideals. for some people this can be teaching, mentoring, creating art, creating stories, anything really. personally for me, it will be a highly individual, alone (no-people) type of career. I want to save all of the limited energy i have with my close friends and family (my I is so, so high), and spend most of my "job" time working on creating something -whether it is my art, music, or writing. Ironically, many people people have told me they see me as "successful" and "together", but they just don't know that i'm actually in the process of leaving current occupation to pursue my passion and a career that is in line with my idealism. might come as a shocking blow to some. :wink:
HTH! and good luck with everything.
