A. A. Milne’s “Happiness” was published in his collection of children’s verse, When We Were Very Young (Methuen & Company, Ltd., 1924). About the poem, essayist Maria Popova writes in “A. A. Milne on Happiness and How Winnie-the-Pooh Was Born,” published on her website, The Marginalian, “Although Alan Alexander Milne is best-known [sic] for authoring the Winnie-the-Pooh book series, he was also a prolific poet. In 1924, two years before the first Winnie-the-Pooh book, he penned When We Were Very Young—a collection of poetry for young children, illustrated by E. H. Shepard. The third poem in the book is a short gem titled ‘Happiness’ — a wonderful meditation on how little it takes to find happiness. (And, clearly, a giant missed opportunity for Apple.)”
