Looking back over my life, I think it's a mistake to seek happiness, fulfilment and material well-being in a single sphere, such as a job. With hindsight, I got by on the latter while avoiding my work actually wrecking any possibility for the first two. It's better by far to seek happiness and fulfilment elsewhere because these three things only line up in a career for the very fortunate few. But they are possible for the many if we each go for a diverse engagement with life.
This is most important for INFJ types because we can be fulfilled within a heterogeneous lifestyle with many components, and this is our natural way to engage with life.
That's not to say the world isn't filled with exploitative, shite jobs - it is! But that doesn't stop us filling our lives with other things that bring both fulfilment and happiness.
