Each fall, Monarch butterflies begin an incredible migration, journeying across North America to a hilltop in Mexico. They focus on their destination, not the difficulties along the way.  Each day, the butterflies take their bearings and set off, allowing instinct and desire to steer them toward their goal. They accept whatever comes: some winds blow them off course, others speed them along their way. The butterflies keep flying until, one day, they finally arrive. Their determination to make it through to the end--just like the determination of a childhood cancer survivor--makes all the difference.
