“And then a man of forty or so, with a French accent, asked, "How do you achieve the presence of mind to initiate the writing of a poem?" And something cracked open in me, and I finally stopped hoarding and told them my most useful secret. The only secret that has helped me consistently over all the years that I've written. I said, "Well, I'll tell you how. I ask a simple question. I ask myself: What was the very best moment of your day??" The wonder of it was, I told them that this one question could lift out from my life exactly what I will want to write a poem about. Something I hadn't known was important will leap out and hover there in front of me, saying I am— I am the best moment of the day. I noticed two people were writing down what I was saying. Often, I went on, it's a moment when you're waiting for someone, or you're driving somewhere, or maybe you're just walking across a parking lot and admiring the oil stains and the dribbled tar patterns. One time it was when I was driving past a certain house that was screaming with sunlitness on its white clapboards, and then I plunged through tree shadows that splashed and splayed across the windshield. I thought, Ah, of course— I'd forgotten. You, windshield shadows, you are the best moment of the day. "And that's my secret, such as it is," I said.”
