After, say, surviving a round of layoffs at your office, you may feel panicked about the prospect of losing your job. Maddux suggests letting go of the notion that there's only one job that will make you happy. "You may think that if you lose your job, you may never find another that's as fulfilling, but that's probably not the case," he says. While you shouldn't deny that your current position might not last forever, it's smart to acknowledge that there will probably be other professional opportunities that could potentially be as challenging and satisfying, he says. Apply this thinking to virtually any setback to bolster your outlook.
