Here is a poem I wrote that does use rhythm. I don't really like it that much though.

Poem #1

You can't turn the colors of the rainbow into black and white/ You can't write the ending to this story so it comes out right/ You don't know until it matters if you're weak or if you're strong/ But no one has the right to say that what you did was wrong.

Tomorrow is a new day that you might not live to see/ The first night is the hardest, yet by morning, you'll be free/ You thought you were invincible but anyone can fail/ It only took a moment for a life's work to derail.

Anybody else could have made the same mistake/ You know it intellectually but still you lie awake/ Repeating like a mantra that you did the best you could/ Asking, "if I die tomorrow, will my friends say I was good?"
