Stress
There shouldn't be too much stress involved in this job unless you screw up big time, as the consequences of a mistake can be disastrous. And, if you work on the retail side of things, you'll be dealing with people, so you always have the potential to induce anxiety. But for the most part, your days should be pretty routine and mellow. And if you're having "one of those days," just pop a Paxil. (Don't really do this. We're kidding. If you hadn't noticed, we do that a lot.)
