Personally, I was never willing to add much stress, but I was always open to higher pay. I don't love supervising people, but I've taken positions supervising small teams sometimes. I currently supervise 1 full-time and 1 part-time, and that's fine. If my boss were to leave, I would not try to get his position (which is basically 100% people management).
I am definitely not a FI or bust person -- we've made lots of choices that delayed our FI over the years (ie having DW stay home for two years when DD was born, moving to Canada from the US) because our emphasis has always been on quality of life (both now and in the future). That said, we're basically at our FI number now, so my tolerance for work related stress is very low. My plan is to ask for reduce hours / more weeks off next year. I don't really want to quit working completely, and I like my current job well enough.
