Local maxima and sunk costs should not in reality be ignored. For example, I could find a better job, but with opportunity costs of paying less attention to my health or my family for a couple of years, and it may be difficult to fully recapture these opportunities later. Or say, I made an effort to get to know my current coworkers well. New job may have better pay and more respect from higher ups, but that's still one thing where I would have to start from scratch with no guarantee of equally good results. It's one thing to look at each problem in isolation, it's another to live a good life overall, which may entail many tradeoffs between different problems.
