Oh boy, what a question! There is and has always been genius of course, those who can pen a masterpiece in no time flat, and others who have the desire and talent and work at it very hard. If you have the crux of poetry which I believe is meter,and add to that the soul of poetry which I believe is metaphor you have the basis for a wonderful poem.
Add to that versification, form, rhyme, and the desire and inner gift, and you have something spectacular.
Anyone can "learn" to write a poem, some
are immortal because the poets are gifted.
This is a great question! Hope this helps.
What is that you express in your eyes? It seems to me more than all the words I have read in my life.
