Choose 4 or 5 categories for minute lists.* If you’re in the middle of a process, then let at least a few of them related to what you’ve been writing in ways that you explicitly understand. Or use these: names of car parts, words descriptive of times of day, graffiti tags real or invented, words of four syllables.
* MINUTE LISTS are a language brain warmup. For each list item, set the timer for one minute and write as many words as you can think of in that item’s category. Write at speed and take anything that comes to mind, even if the words popping up are incorrect matches or not real words. The speed and free-for-all ethos are aimed at getting your vocabulary moving.
