tough choice...
I am also having a difficult time "deciding" on what to actually do with myself career-wise. There seems to be some sort of pattern (as noted in various posts on the internet) among INFJs and Psychology based professions... I could be completely off about this, but that just seems to be what I have noticed.
I have taken small steps in multiple directions, to find that I was weary of most things, until I landed on Psychology. Even still, I cannot completely make up my mind, and I am 26 years old, so I should get onto that career path pretty soon! First, right after high-school, it was Art for me. After only one semester, I decided to work and travel a for a bit, picked up surfing, and did that for a few years. I then decided I wanted to be a nurse... I completed the practical nursing program, with hopes to carry on and become an RN. After 1 1/2 years of working as an LPN, I realized I would probably destroy myself with self-criticism, and fail miserably as an RN due to my HUGE lack of ability to be assertive. I have now been an LPN for 4 years, and utterly exhaust myself each work day due to the fact that I over-empathize with my residents/patients and their families, and make every possible attempt to please all on-shift staff (which is a very impossible task!)...
So, two years ago I went back to university part-time, just to open myself up to other options. After completing first year psychology, I decided to work towards a BA, major in Psychology. I'm still working as a nurse and attending university... I do not know what type of job I will land in the end, but so far I am leaning towards special education (assisting), working in community support, or recreational/activity work, assisting older adults, and/or individuals with special needs.
