There's a few, but maybe the most relevant one is that my work probably doesn't really matter too much, and it's not work stressing about. In my early twenties I had some ego about whatever esoteric UX thing was on my radar at the time, thinking it was worth a bunch if time to get right and in some cases even compromising getting things done in time. Sometimes they matter. Sometimes performance matters. Sometimes accessibility and usability matter. But never enough to really get hung up on, particularly if the person paying you doesn't care. So the mindset change is to do the best feasible work within the constraints given, and no more than you're paid for, because it's not at all worth it. Mental health and well being are the most important things to preserve. Nothing else matters as much, not the well-being of others, not charity, not broader social problems, not deadlines or money, but all of those might have some impact on your mental health as well. It's a tough one. Don't care first about other people, but care about others when you can afford to. Anyone guilting you about social issues is either bourgeois or wants to be.
