If you want to see something done, just tell some human beings it can't be done. Make it known that it's impossible to fly to the moon, or run a hundred meters in nine-point-nine seconds, or solve Fermat's Last Theorem. Remind the world that no one has ever hit sixty-two home runs in a season. Stuffed eighteen people into a Volkswagen Bug. Set half the world free. Or cloned a sheep. Dangle the undoable in front of the world. Then, consider it done.
