Question

I have a question for all the poets and poetess, How do you know the grammar of your poem is right, and mine is wrong? When I write in my home language that I was born? I am South African, you Italian or maybe American. I write and speak in a different way, Not always how you would say. But does it make my grammar right and yours wrong? We all writing down our emotions, dreams and fears, Is that not more important here? I like painting my emotions on your poetry wall, It makes me feel good to display them all. So please, give me a break, Even if you think I make grammar mistakes.
