Happened to me. I'm very pragmatic but I'm more idealistic than pragmatic. I was well payed while on the industry but wasn't happy with what I did. I basically did thing for which I hated the industry and developed products with abuses which I used to fight against.

I left my job and now I work as a teacher. I doesn't pay well, it is much more work, I had to leave the city I was living in but I now feel I'm not doing anything I think is unethical and I have much more autonomy to decide what I do.
