This is obviously not the easiest type of assignment as most of us do not get to do that often. The main suggestion for writing a brilliant piece of poetry is to use your soul/ heart and imagination. This combination will bring you up to the best result. Of course, do not forget to choose the topic of the poem essay. Is it like a love story, patriotical hymn or suffering cry? Just go for one you need. It is very important to choose the rhyme and length of it, too. Once you did it, find the nice place where you can relax, close your eyes, imagine your poem like a painting and words will come up to your mouth.
