When you only have two options, find a third.
You were offered a job in Mexico, por ejemplo, but you do not want to move to Mexico, you want to stay in Montana. Do you uproot your entire life? Or turn down the job? Both are unappealing choices, and the minute you begin to fret about which one of them you should pick, you must stop—and turn to someone outside the situation (anyone, really) for a third idea. This is the person—as wise or as ordinary as the rest of us—who will shrug and say, "Why not ask to telecommute?" There are always more than two options. Sometimes, you just need two brains to remember that.
