I recommend the book The Wisdom of Donkeys, Finding Tranquility in a Chaotic World, by Andy Merrifield.
My only caveat is that you might find yourself in dire need of a donkey of your own, though you can use your imagination until you find one.
From the beginning of the book:
Time slows down amid donkeys. In their company things happen quietly and methodically. It's hard to forget their innocent gaze. It's a calm that instills calm. Your mind wanders, you dream, you go elsewhere, yet somehow you remain very present. Milan Kundera says in his novel Slowness that speed, the demon of speed, is often associated with forgetting, with avoidance, and slowness with memory, with confronting. We move slowly when we want to listen to ourselves, to others, and to the world around us. We move slowly when we want to confront ourselves. If only we could slow down! The rush of contemporary life overwhelms our ability to observe, to hear, to step back and wonder, and to meditate. Our society, Kundera says, wants to blow out the tiny trembling flame of memory.
