Wedding vows are supposed to be sweet proclamations of two people's love to each other. In reality, they're a series of tumultuous tests.
"Of course you'll love me when I'm rich, but how about when I'm poor? When sick? Every single day until we're both dead? OK, deal."
Luckily, you take no such vow when you accept a job. Sure, you stick with it through the bad times (when you have to pick up your boss' dry cleaning) and through the poor times (when you know you deserve a bigger paycheck). And even if you really enjoy your work, you have your limits, and crossing the state line might be one of them.
