I recently rediscovered a rare moment of inspired creativity I had left as a comment to this article back in March, 2008, “No Resistance is Futile”.
The form of haiku—
Like banks of a river flows
The point of the article, and the website too, is that limitations, restrictions, or boundaries narrows ones focus and fosters creativity. One often struggles and complains about boundaries and limitations, but it is this very struggle that develops the creative muscle needed to flourish within those walls. (An analogy seems to apply to prayer too.)
This reminds me of Twitter. A limitation of only 140 characters places a steep premium on the economy of words to convey an idea or to paint an image. People manage okay, but good story telling, or even poetry, is rare. I try.
