It doesn't have to be boring to you. But I will admit that as a college student, when I had a summer internship in a government computer facility, I came away with the impression that while I enjoyed programming when I could do it on my own terms, an actual programming job would be boring.

But instead of boring, you could substitute unpleasant or unglamorous, and the point still stands pretty well. For instance, fixing a toilet is usually not particularly hard, but something that most people are repulsed by.
