Interesting.. checking back on this thread, it looks like a fairly even spread of job satisfaction across all F/T and P/J types. It's still too early to draw any real conclusions from this though, as the sample size is still very low..
I don't know why I feel like no matter what job I work, I can't seem to be happy for long. Maybe I'm just too idealistic/unrealistic with my standards? If you were to ask me what my ideal job would be, I'm not even sure I could tell you precisely. I feel like a jack-of-all trades, master of none. At my lowest, I feel like my gifts just aren't meant for this crazy modern world we live in, and that I would be happiest living a quiet life out in the mountains somewhere.. but that just seems like a romantic pipe-dream that in reality would actually be a lot of hard work with plenty of stress along with it.. Ugh!
All I can say is that I want to feel like I'm using my best strengths to somehow make a positive difference in the world in line with my values. I'm 28 years old and I feel like I still have to try things and learn by experience in order to figure things out and narrow down what will make me satisfied in my career. Part of it is from gaining a better understanding of myself, which I owe much gratitude to MB Theory for helping me understand what makes me different than others.. I wonder if most INFP's end up feeling like the have to "sell their soul" to make a decent living, pursuing their creative interests on the side.
Here's to the ongoing journey that is life! I hope I'll eventually find my calling, so I don't feel like a useless lost soul :)
BTW I really enjoy reading everyone's feedback on this.. Thanks @sittapygmaea
