I've been asked this before - "How do you know what to write? Where do you get the ideas?"
I like Timothy Liu's quote: "When you go to bed, you can't force a dream, right? In fact, the dream is a gift because it's a surprise. There are different theories about where dreams come from, but a general one is that the day's residue often becomes the little grain of sand around which the dream will then build. i think a poem is like that."
To me, poems are little birds floating around my head. I just have to stop and listen to them.
I often close my eyes and type, just listening to the thoughts and words being fed to me.
I've had times when I cannot write poetry and I know it's due to much noise in my life. Until I can resolve or push the noise away, I cannot hear the words.
So poetry is all around us - the stars, the moon, struggles of humanity, our child's eyes, our pasta sauce.
