Seeing a shooting star, watching a butterfly flutter its wings, blowing bubbles, boarding a boat... When we're young, many things surprise us. Each first experience is unique and unrepeatable, and our capacity for wonder and fascination seems endless. The problem is that, as we grow older, this capacity atrophies, as if we've run out of that "surprise reservoir" with which we once came into the world. And no one teaches us how and where we can refill it.
