This is exactly what I noticed, 12 line, which also led to the use of ABAB rhyme mode. So if you realize this, then you will naturally ask for help to write a clutch poem instead of just 12 lines. If you haven't noticed the style of this poem, you can consider using it in the future.
The word itself reminds me of the "seven times nine" character in Star Trek, because she often mentions the necessity of change, which also refers to the Borg. So fans of Star Trek series can write in this style or genre. Or just how human beings continue to strive to improve themselves through wisdom and technology. This is just like the experience of choosing learning curve in higher education and the experience of choosing learning curve in office or factory.
Another view is that Darwin wrote about evolution and species adaptability decades ago. Or you can write about the development of artificial intelligence and how it will change the future world. Or you can write about how disabled people must adapt to their problems and still be useful at work or at home. This may explain how medicine has improved their lives.
Or you can write a character with super powers, just like in the sci-fi TV series smallville. As time went on, clark kent gained more super powers, even when he could fly. This is just an important conclusion of a poem, but I hope it is optimistic or inspiring.
If you choose a family theme or a romantic theme, there will be enough examples to illustrate how people must adapt to what life provides or takes away. If you choose animals as the theme, then you can consider endangered species, or world pollution makes animals endangered species.
Therefore, although the rhyming or non-rhyming range of poetry can help you, the choice still depends on you as a poet. You can start with a word or phrase. The first line will help you follow it to the second line, and the ends of the two lines will help you rhyme. My choice is 8-6-8-6 syllables in the normal rhythm hymn style. I uploaded more than 2,900 poems to poemhunter's poetry website, and many of them were created by it.
