I love to do exercises that get me writing in a way that I'm less familiar with. For you non-poets out there, here's something that will help you get out of your comfort zone and stretch your little-used poetry muscles (we all have them, but we don't all use them).
Write a list poem!
A list poem is simply a list of related things in the form of a (usually) rhyming poem. Check out my summer poem and/or my 200th blog post to see some examples, then try one yourself.
Have fun with your list-writing!
