I do! I've actually had one there since 2011, when I printed out and placed in my wallet a poem said to be by the Persian poet Hafez, "The Sun Never Says." It's since been determined that it's actually by Daniel Ladinsky, an American Sufi who says he heard Hafez recite the poem to him in a dream, and it's getting a little raggedy around the edges, so I decided to reprint it with the correct attribution. (It's still a great poem, in my opinion.)
Then I decided to print another poem on the back: "You are As You Are" by Rumi. One goos Sufi poem deserves another, right?
Then I printed four more poems: "spring song" by Lucille Clifton, back-to-back with "Love (and the Meaning of Love)" by Nikki Giovanni; and "God says yes to me" by Kaylin Haught, back-to-back with "What is the opposite of pillow?" by Richard Wilbur.
So now I have six poems in my pocket, tucked into various compartments of my wallet to rediscover periodically. That should hold me for a while.
