Jim Lovell, the commander of Apollo 13, knows something about workplace problems. When I’m confronted by a particularly onerous challenge on the job, I try to remember Lovell’s philosophy on the matter:

Be thankful for problems. If they were less difficult, someone with less ability might have your job. —Jim Lovell

He’s right, of course. If it weren’t for the vexing, taxing, seemingly intractable problems of our job, someone much less hard-working, focused, and motivated could do it. And they’d be cheaper, too.

Problems are frustrating, sure, but they’re also job security.
