It is entirely job dependent. I have been in jobs where it was just a grind and going the extra mile simply put a smile on my boss's face. In jobs like these the best thing you can do is carve out as many hours as possible during the work week to build new skills or apply to other jobs. I've also been in jobs where going the extra mile directly contributed meaningful skills to my resume/portfolio and helped me get a new job with way better pay.
Eh, going the extra mile is how I went from customer service agent to senior server engineer in 5 years (with the same company).
There's always a balance between the two, but the most important thing is knowing how to say no without sounding like you're saying no.
