Today’s exercise can be found here. This is in honor of a list going around of bad student metaphors. I actually had a copy of this list ten years ago as a grad instructor. It has not lost its humor at all. Metaphors should be seamless. They should fit so well the reader doesn’t have to think about them. At the same time, they should amplify and expand your writing. They help you do work that otherwise could take paragraphs. It’s an art.
After you do the exercise above, look for metaphors in your own writing. Do they work? Do you need to rewrite? Practice practice practice.
