Take or write a story or myth, continue to rewrite it over & over, or, put it aside &, trying to remember, write it five or ten times (from memory); see how it's changed. Or, make a work out of continuously saying, in a column or list, a sentence or line, & saying it over in a different way, ways, until you get it “right”. Save the whole thing.
Typing vs. longhand experiments as recording/creating devices/modes. Do what you do least.
Make a pattern of repetitions.
Take an already written work of your own & insert (somewhere at random, or by choice) a paragraph of section from, for example, a book on information theory or a catalogue of some sort. Then study the possibilities of rearranging this work, or perhaps, rewriting the ‘source’.
Experiment with writing in every person & tense every day.
Explore possibilities of list, puzzles, riddles, dictionaries, almanacs for language use.
Write what cannot be written, for example, compose an index. (Read an index as a poem).
