Minute lists activate your word brain. Set a timer for one minute, and for each list assignment, write any word that comes to mind under the list heading even if it’s a wrong answer (out of category or a phony word). Start the following list immediately when the timer rings.
Decide in advance on 4 or 5 word lists then write them continuously. Here are some to use for today if you want: names for fruit desserts, words related to memory and remembering, words that start with the letter D, names you could give a pet salamander, street names (real or invented).
