How is poetry used in life?

Poetry can be used as many things. Poetry can express how you feel or what's on your mind or how you are feeling like the piece of poetry that I've always found my favorite was this one here. "Some people were born with stars in their life but their souls were lost at sea and other were born with tornados in their life but their eyes shined with glee." I've always been fond of that poem. If you understand it then you'll understand why poetry is used in life.

It is sometimes used to express sadness, and even rap.
