“Someone once told me that children are like kites. You struggle just to get them in the air; they crash; you add a longer tail. Then they get caught in a tree; you climb up and bring them down, and untangle the string; you run to get them aloft again. Finally, the kite is airborne, and it flies higher and higher, as you let out more string, until it's so high in the sky, it looks like a bird. And if the string snaps, and you've done your job right, the kite will continue to soar in the wind, all by itself.”
