Getting stuck is often the result of trying for perfection. You can’t find the perfect word or phrase and can’t seem to write anything till you do. When that happens–assuming that you have consulted your thesaurus and gotten a drink of water and done a head stand for 30 seconds and done all the other things that usually work for you, try this. Keep your pen on the paper or your fingers on your keyboard and write writing. Do not stop. Write whatever comes into your head. It probably won’t be related to your story. That doesn’t matter. If you can’t think of anything else, just write, “I can’t think of anything” over and over again until something breaks. It will.
