Fast forward to my university and I was taught something completely different in a creative writing course — poetry is about play. It isn’t about having to inspire some deep meaning. Sometimes it can just be fun to mess around with words in a way that sounds pleasing. As others have mentioned, there’s also this notion pushed in our youth that poetry has to have perfect rhyme, or follow some scheme; but as soon as you realize that isn’t the case, combined with the fact you don’t have to be searching for some obfuscated truth within poems, you start to realize poetry has been marketed as something much different than what it really is.
That’s not to say you can’t search for deep meaning in a poem, or attempt to write something meaningful into one - but really, poetry is about play, and it should be as serious as you want it to be. For me, that realization made me “get” poetry more than I did back in my high school days.
