"When did you become a poet?" Stafford is reported to have said,See, what limits do you put upon yourself?
"That is not the right question.
The right question is: When did you stop being one?"
You may very well have poetic capabilities. Don't close yourself off to them.
I claim that if you can twitter you can write a haiku! The restrictions are very similar. The one GREAT benefit Twitter has over a printed haiku is the ability to link. But if you haiku (or sherku) on a web site, that advantage is nullified.
There are more limits being explored this month over at the Joyful Jubilant Learning blog. Joanna claimed "But I'm not creative!" amongst the several posts exploring learning from failure.
Stay tuned to explore more limits!
