A thousand origami cranes – you fold them, make a wish, and… see what happens. Aside from the “prize”, this is an amazing endeavor. I tried it and concluded that the experience is worth the time, effort, and paper involved. It was self-revealing, a great exercise of patience and persistence. By the time you finish all cranes, the lesson is learnt!
