I retrieved this creativity quote from an interview by Krista Tippett with the poet Naomi Shihab Nye. Here's an excerpt from the interview where Nye describes what she means by "you are living in a poem."
I just came back from Japan a month ago, and in every classroom, I would just write on the board, “You are living in a poem.” And then I would write other things just relating to whatever we were doing in that class. But I found the students very intrigued by discussing that. “What do you mean, we’re living in a poem?” Or, “When? All the time, or just when someone talks about poetry?” And I’d say, “No, when you think, when you’re in a very quiet place, when you’re remembering, when you’re savoring an image, when you’re allowing your mind calmly to leap from one thought to another, that’s a poem. That’s what a poem does.” And they liked that.
Listen to the full interview here. It's well worth your time.
