Signs it's time to find a new job

Good lawyers generally spend their entire career at one firm, and Dad was a good lawyer. Mom was an architect, but quit when she gave birth to me, volunteered at my sister's and my school for 14-ish years, then worked at the Art Institute of Chicago for something like 15 or 20 years. It rarely occurred to me that changing jobs was commonplace for responsible adults. You find someplace good an you stay there and do good work and everybody is reasonably happy.

Apparently that's not the case. My wife's family knows this very well, but... they're federal government employees, so I thought they didn't count. Oh well. Here are some signs it might be a good idea to move on.
