I think all poetry is challenging to write..In High School I forced myself to write poetry as a contributing editor for the school paper but it was forced. I followed the rules or writing..but that was all..
True poetry is something that moves you, the author. It does not matter what subject your write about nor do the measures..rhyme, rhythm, count. It can be a Haiku or a prose poem..
What is important is your feeling as you are writing the poem and how you feel when you have finished writing the poem..
