Art of Poetry

I'm somewhat getting the concept of poetry, its the act of putting emotions on paper, like the sad ones that make me think woe is me, an the bad ones I think should stay there, it could be short, it could be long there is no right decision, There's a lot of ways it could go wrong like not having precision, With the words you use and how you use them, you want emotions to be intense, Or it will just cause confusion, and not make any sense.
