You don’t need rhymes to write poetry. Often rhymes ruin the message you’re trying to get across. You use a word that rhymes, but detracts from your point.
We of an older generation (me, for example) seem to have an idea that all poetry should rhyme. Rhyme works for fun little poems, for songs and for some children’s poetry.
If you want to write rhyming poetry, be prepared to work hard. You’ll have to master rhyme AND meter. In my opinion, poetry is the highest form of writing. Don’t smudge your paper with inadequate rhymes.
