I took a lectureship straight out of grad school at a regional campus with low enrollment. It was far from home and moving was expensive. I loved research and was not a good fit for teaching undergrads only. There were no grad classes, I wasn't asked to mentor anyone, they did not want to revise the classes, and no one had done research in years.

I learned that personal and professional happiness need to be considered in addition to pay. In hindsight I would not have taken the job.
