(author here) I've always found this advice a bit of a double edged sword. I absolutely agree that it'll develop your career, but I don't really want my day job to become 100% drudgery because I'm the only one who bothers to do it properly.

If the untouched system is just fiendishly complex this can be fun to figure out, but if the untouched system is pure pain to deal with, I think I'd rather risk unemployment.
