Consider for a moment that you decided you wanted to do something where you had few skills to apply or knowledge of, nor a social network to rely on. You worked incredibly hard to get yourself where you are today for your current profession, despite that the career no longer serves your interests. Let’s consider that you also went to graduate school — got an MBA from a top program — and you are a really hot-stuff manager. You have a mortgage, student loans, credit card debt, and a family to support.
It’s not that hard to understand why you’d stick with your local maxima — You have a lot to lose by doing so and constraints. Therefore, to add to your argument: discounting AND loss aversion play a role in the decision made to stay en route.
