You can care about your career and your self improvement while still maintaining healthy boundaries around the mental effort expended for your job. We’re in it for a long time but jobs come and go
If you don't care about what you're doing, you're spending most of your influence on the world on something you don't care about.
If my choice is between working at a boring job where I can support my colleagues, and an exciting job with cool tech where people are having mental breakdowns and nobody has the mental space to support them, I'll take the boring job where people don't care about stupid directives and dealines from above.
