Both scenarios are stressful in different ways. As much as I enjoyed the problem-solving aspect of all of my jobs in the hotel industry, and some at a high salary, Option A is more attractive.
The SO and I are fairly frugal without lowering the standards of living. He has held the same job with the same company for 25 years because he values the virtually stress-free environment and can leave work without having to think about it until his next shift. His job and simple lifestyle has not left him wanting. The house that he bought a couple of years ago is fully paid off. There is no reason to own a car. National Health covers medical needs. Food and heat are the biggest costs, but he earns enough to cover those and still have money for play. My savings are set aside to supplement retirement. If I get a job again, it would probably be in a low-stress position.
