This thread contains a story. The story itself is wholly unremarkable, except for the fact that I wrote it backwards (start from the linked comment and read
upwards, until you get to the comment that starts: "Maybe I should start.."), entirely off the top of my head, without copying from a script and pasting backwards. Wow, what a workout (for a writer).
What sorts of writing exercises have you put yourself through? Which do you do regularly?
