Weinberg in one of his consulting books suggested replacing "just" with "have a lot of trouble" (as in, "we'll just add this feature" with "we'll have a lot of trouble adding this feature") and "should" with "isn't" (as in, "that information should be kept here" with "that information isn't kept here"). It's surprisingly effective. I think there was another such magic word or two on his list, but don't remember what they were.
