This is a personal question, and therefore, only you can answer it properly. However, we can provide an example to guide your work. As the topic and subject matter are not included here, I will chose the subject of reading.
<em>There is nothing I love in this world more than reading,</em>
<em>I just can't describe how I love this magical feeling.</em>
<em>I am immediately transported as I sit in my nook,</em>
<em>and to a hundred different lands I travel when I open my book.</em>
<em>Bang! Bang! A gun cuts through the air in the Old West,</em>
<em>And the kiss of a prince awakens a princess from her rest.</em>
<em>Robin Hood appears and reminds me to be bold, be brave.</em>
<em>And with Aladdin I see a million wonders within the cave.</em>
<em>The things I can discover within the pages never end,</em>
<em>and that's why books willl aways be my best friends.</em>
In this poem, I use onomatopoeia, alliteration and rhyme. Alliteration is a device in which several words that are close together have the same initial consonant sound. I use this device in "be bold, be brave." Onomatopoeia is a word that phonetically imitates the sound that it describes. I use this device in "Bang! Bang!"
