As one online colleague posted, "The work is infinite. There is always one more thing you could, should, would like to do." The industry encourages workaholism.
Another quote that is spot on:
Most professors I know feel impotent. They may be forced into either coddling students, watering down curriculum, or passing students who have not earned a passing grade. Those who do not give in may find themselves labeled as "outdated" or, worse yet, a political outcast. In today's consumer-driven world, holding the line is becoming more and
more dangerous--not only for institutions, but for individual professors as well.
It's still a great job. I can't even imagine having any other type of job.
