I turned down a better paid, lower stress role recently where I would have been working with good people I liked and had worked with before.

Main reason was a sense of mission. If I screwed up in that role, a billionaire would have been a tiny bit poorer but literally nobody else would care. My current role involves critical global infrastructure, everyone would notice if we screwed up.

Having said that, money is still very important. I am pretty well remunerated - more would be nice but I'm not hurting.
