Many years ago I entered one of the quarterly “24 Hour Short Story” contests at Writers-Weekly.com. Essentially, the idea was to write a story based off of a single first line, no longer than the given word limit (1,000 words in the case of that particular contest), within 24 hours. Now I am by no means a fast writer. It may or may not have taken me forty-five minutes just to write the last three sentences. But it sounded like fun, and 1,000 words was surely doable.
For example, as the saying goes, this picture alone is worth 1,000 words.
Not sure to whom, but an aphorism is an aphorism.
