Odds of Hanging On
The only people we see excelling in this job for long periods of time are devout Zen Buddhists. Okay, perhaps that's a bit of an exaggeration. So maybe you don't need to find a map to nirvana under the Bodhi tree in order to join the ranks of the FAA's safety inspectors, but if you happen find yourself with inner peace to spare, hyper-concentration powers, and an unnatural mastery of stress management, you're probably going to have an easier time of things.
On the other hand, if you're the sort of person who can handle repetition and stress for a little while, but then secretly begin building to a breaking point like bowl full of boiling ramen noodles with the lid left on the pot, then you'll probably be looking for another job within five years. Maximum.
