What helped me a ton to disconnect from some of this sort of stress is building up a bit of a savings buffer. Once I had a few months of savings around I suddenly started to give much less of a shit about day to day work as I could, if I really wanted, just walk away. I am "lucky" in that I have no real dependants and my partner and I have decided against kids so there's none of that to consider.

Ever since I entered my thirties I've been increasingly "selfish" when it comes to my time. No job is worth it.
