I'll start. I've had a few jobs in my career. My last two jobs were in software engineering and education.
People think being a software engineer means you can troubleshoot hardware problems.
People think that if you're a professor or teacher, student performance is directly correlated to instructor efficacy. You'll get hounded over the 10% that fail your class rather than the 10% that get A's.
That as a retiree, you sit around the house doing nothing all day.
Oh..., yeah, that part is kind of true.
