Hi Matej! about the reason:
"I wasn't happy with the work I was producing and and I couldn't change that"
It would be interesting to go deeper and see if the responders where experiencing what I described in this article:
which at the end explains how UXers end up to leave the business or stay and basically do shitty work.
I think that the core problem it's not the UX maturity or the lack of career progress, but it's
"[...] I couldn't chage that"
lack of cognitive flexibility and resistance to change as psychologically factors that prevent to change by rising so the ux maturity bar, introducing career paths etc
