Writing short stories with a limitation on word-use is an excellent exercise to produce clear and lean prose. At https://www.sffchronicles.com/ (a forum/community for writers of SF & Fantasy) exercises like these are shaped as monthly challenges, complete with preset theme and genre, for stories with a maximum of 75 words. There are also quarterly challenges for stories with 100 and 300 words. Below are a few examples of some of my entries for those challenges.
