Once upon a time, there was a traveler on horseback who finds himself facing a swamp. And he doesn't know whether to go around or try to wade through. The traveler asks a local boy: "Tell me, local boy. Does the swamp have a hard bottom?" And the boy tells him that it does. So the traveler guides his horse into the swamp and they begin to sink deeper and deeper into the muck. He shouts to the boy: "I thought you said it has a hard bottom!" And the boy says: "It does, Mr. Traveler. You're just not there yet."
