People usually write poems because they want to capture a moment or certain emotion they have experienced. Poetry employs a different approach to communication with the reader. This genre of literature has its own devices and techniques to convey your experience to the audience. Practice makes perfect, but if you write poems, or at least tried to, you know that prior knowledge of these techniques is extremely helpful.
